"GU-PU-KRA

Gu-Pu-Kra is the homeworld of the Gubprwufu. It is a rocky world some 14500 kilometres in diameters [114% the size of the Earth] with a density some 12% greater than that of the Earth, giving it a mass of some 165% that of the Earth and a surface gravity of some 1.27 times that of the Earth. As for its co-planets of Pgduo and Upopeb, Gu-Pu-Kra orbits Rp'Gu at a distance of some 8.25 million kilometres [0.055 AU; some one seventh of the distance at which Mercury orbits the Sun], taking slightly less than seven Earth days to do so.

Due to the small radius of its orbit, from the surface of Gu-Pu-Kra, Rp'Gu appears to be some 7.7° in diameter [some 15 times larger than the Sun does from Earth, covering 225 times the area in the sky]. However, because of the much lower luminosity of Rp'Gu compared to the Sun, it is also much dimmer. From Gu-Pu-Kra both Pgduo and Upopeb subtend an angle of roughly 2 arc minutes. This means that human vision [with an angular resolution of some 1 arc minute] would be just able to resolve them as discs. From Pgduo and Upopeb, Gu-Pu-Kra appears to be some 0.1° is width [roughly 20% the size of the Moon in the skies of Earth], easily resolvable as a disc to a human-like eye.

As for Pgduo and Upopeb, Gu-Pu-Kra is tidally locked to Rp'Gu, and as such rotates on its axis in a period equal to its orbital period of slightly less than seven Earth days long, so that one face of Gu-Pu-Kra always faces Rp'Gu and so is in permanent daylight while the other is permanent night. It has an axial tilt of some 9° [the Moon, which is also tidally locked, has an axial tilt of some 6.7° to the plane of its orbit].

Gu-Pu-Kra has a highly circular orbit around Rp'Gu due its being circularised by tidal forces within a relatively short time (geologically speaking) of its formation. Because of the dynamics of their orbits in the Trojan points of Gu-Pu-Kra, and their smaller masses, the worlds of Pgduo and Upopeb oscillate far more in position and so suffer far larger tidal forces, which in turn drives their extensive volcanism.

Even so, its orbit close to Rp'Gu and the presence of the co-planets Pgduo and Upopeb mean that Gu-Pu-Kra experiences tidal forces significantly more powerful than those felt by the Earth and is perhaps ten times more geologically active than it, with major volcanic eruptions and so on being consequently more frequent. Thus supervolcanoes, earthquakes and so on are a significantly greater driver of Gu-Pu-Kraian evolution than is the case on Earth.

Another effect of this is that the core of Gu-Pu-Kra is rather hotter than that of the Earth and the crust rather thinner. This means that the surface of Gu-Pu-Kra is divided into roughly ten times as many tectonic plates as is the case for the Earth, which of course are, on average, smaller than those of the Earth. These tectonic plates also move considerably faster than those of the Earth [anything up a metre a year, compared to less than 10 centimetres a year on Earth]. As a result of this, there are roughly ten times are many mountain ranges on Gu-Pu-Kra as on the earth, many of which are relatively young and thus relatively high and steep, and correspondingly many subduction zones where the crust of Gu-Pu-Kra returns to the interior of the planet in deep oceanic trenches, so that the surface of Gu-Pu-Kra also has quite a lot of small lakes, island chains and so on. This also means that there are fewer old and stable parts of the crust (cratons), and what there are of these tend to be small. This would hinder any investigation into the geological history of Gu-Pu-Kra.

A side effect of the tidally stirred molten core of Gu-Pu-Kra is that, despite its slow rotation relative to (for example) the Earth, the strength of its magnetic field is some two and a half times greater than that of the Earth [roughly 0.8 gauss as opposed to 0.3 gauss for the Earth], and highly aligned with Gu-Pu-Kra's axis of rotation. This, together with its proximity to Rp'Gu and so the higher density of the solar wind from it compared to that Earth receives from the Sun, means that Gu-Pu-Kra has frequent and very bright aurorae).

Some 76% of the surface of Gu-Pu-Kra is covered with water [as compared to 71% for the Earth]. Even taking this into account, the relatively larger size of Gu-Pu-Kra compared to the Earth means that the land area of Gu-Pu-Kra is some 107% that of the Earth. A contour map of Gu-Pu-Kra shows how this land is arranged on the planet.

The atmosphere of Gu-Pu-Kra is some 2.2 times thicker than that of the Earth. This high atmospheric pressure means that the boiling point of water on the surface of Gu-Pu-Kra is 123°C. In composition the atmosphere is mostly made up of nitrogen gas and contains no free oxygen so that it would be un-breathable to an unprotected human being. It also contains a large fraction of carbon dioxide, water vapour and volcanic gases, in particular sulphur and nitrogen compounds. The atmosphere of Gu-Pu-Kra generates a high level of natural greenhouse effect, some 160% that of the Earth, which raises the temperature of the planet to some 15.4°C [288.5K] sufficiently for water-based life to be possible there. The lack of ultraviolet radiation produced by Rp'Gu means that Gu-Pu-Kra does not have, or need, an ozone layer.

The composition of the atmosphere of Gu-Pu-Kra is, like that of the Earth, very different to what it would be without the presence of life. That is, it is in a state that is largely governed and maintained by the life it sustains. Although its composition is very unlike that of the Earth, particularly in its lack of free oxygen, its composition would still indicate that processes beyond those of a lifeless world are taking place there, even without any other clues that might be present [such as a technological civilisation!].

The chemistry of Gu-Pu-Kra and its ecosystem means that all water there (and so all rain) is somewhat acidic, mainly due to the presence of nitrogen compounds that make it into weak nitric acid [not unlike acid rain on Earth], though with a smaller amount of sulphuric acid mixed in from atmospheric sulphur compounds. It also contains significant quantities of dissolved nitrates, to the point that, were it to exist on Earth it would be classified as suffering serious nitrate pollution. Neither of these factors are, however, a problem for the life forms of Gu-Pu-Kra as they have evolved to live in such an environment.

The long history of life and active geology of Gu-Pu-Kra means that there are plentiful oil and gas deposits on Gu-Pu-Kra. The more active geology of Gu-Pu-Kra compared to the Earth means that there are more of these than on Earth, and also that they replenish faster (though still over geological time!). Of course, oil does not burn on Gu-Pu-Kra but it still has many uses in industry despite this.

The higher gravity of Gu-Pu-Kra means that its atmospheric pressure drops proportionally faster with height than is the case for the Earth [that is, its scale height is 1.27 times lower than that of the Earth], so that the edge of space is only 83.5 kilometres above the surface of Gu-Pu-Kra [rather than 100 kilometres above the surface of the Earth], despite the level at which the pressure of Gu-Pu-Kra's atmosphere is equal to that of the Earth at sea level being roughly 4700m [15400 feet] above the surface of the planet.

Because of the tidal locking of Gu-Pu-Kra to Rp'Gu, somewhat less than half of the land surface of Gu-Pu-Kra lies on the far side of the planet to Rp'Gu, and so never sees direct sunlight, although most of it is not entirely dark. This side of the planet becomes progressively colder away from the terminator between the day and night sides of Gu-Pu-Kra.

Because of its thicker atmosphere and larger mass of water on Gu-Pu-Kra, which helps to hold and distribute heat more effectively than is possible on the airless surfaces of Pgduo and Upopeb, the mean temperature of Gu-Pu-Kra is some -40°C. However, because of its tidal locking to Rp'Gu the point on its surface where Rp'Gu is at the zenith reaches some 106°C - which is not enough for the ocean there to boil - while the centre of the night side opposite this point drops to some -100°C, which is enough for the surface of the ocean there to be frozen. All of this means that Gu-Pu-Kra is far warmer than its co-planets.

In addition to this the temperature of Gu-Pu-Kra can drop significantly during those infrequent times when starspots reduce the luminosity of Rp'Gu by up to 30% for periods of up to Earth months. However, these temperature drops do not cool the planet to the point that the surface of the dayside ocean can begin to freeze [due to the thick atmosphere, high greenhouse effect, large reservoir of heat within the ocean and the active volcanism of Gu-Pu-Kra].

Because of its tidal locking to Rp'Gu, low axial tilt and short orbital period there are no seasons as such on Gu-Pu-Kra. Instead, temperature and weather on its surface are determined by distance from the point directly below Rp'Gu more than by any other factor.

The intense solar heating at the point closest to Rp'Gu heats the air at that point and drives the evaporation of water from the surface of the ocean there. This leads to vast updrafts which form a constant rising column of air which in turn pulls in cooler air from the surface around it. This process drives a vast hurricane centred under the zenith point and extending some 45° out from it so that it covers some 14.6% of the surface of the planet (29.2% of the sunward face). [Note that this hurricane depends on being over an ocean for its existence; as such there may have been periods in the past of Gu-Pu-Kra when the motion of its tectonic plates moved a continent under the zenith point, dissipating the world-hurricane for the duration of its presence.]

On the opposite side of Gu-Pu-Kra, in the centre of the night side, a vast downdraft matches the updraft on the day side. This is not associated with a permanent storm, however.

In between these two extremes the atmosphere is divided into a series of spherical segments, all centred on the zenith point. Unlike the equivalent circulation on Earth, which runs parallel to the equator, on Gu-Pu-Kra it circulates around the zenith point and so is aligned with the terminator.

One difference that humans might well notice about Gu-Pu-Kra is that in most places shadows there are much shorter than they are on Earth. This is because Rp'Gu is so much larger in the sky than the Sun is on Earth. The Sun is some 0.5° wide in the sky; when it is just above the horizon this width means that a shadow cast by it will converge to nothing in a distance of some 115m, which is quite a long distance. Rp'Gu, on the other hand, is some 7.7° wide - some fifteen times larger - and because of this shadows under the same circumstances are less than 7.5m long, and much more obviously converge over that distance.

THE ENVIRONMENTS OF GU-PU-KRA

The surface of Gu-Pu-Kra is divided into five regions, radiating out in concentric spherical segments from the hottest point directly under Rp'Gu. These consist of:

Du-Bepdh. The core of the world-hurricane. This is region where the hurricane is fiercest, driven by water temperatures approaching the boiling point of water on Gu-Pu-Kra. There is no land in this region of Gu-Pu-Kra, and no macroscopic airborne life can survive the winds there. There is extensive microscopic life in the water, all of it what on Earth would be considered hyperthermophillic to survive the high temperatures there, and also a great deal of aeroplankton. This region extends out some 45° from the point closest to Rp'Gu and so covers some 14.6% of the surface of Gu-Pu-Kra.
Duo-Uap. The periphery of the world-hurricane. These are regions where the world-hurricane is still very fierce - too much so for civilisation at a 2011 level of technology to survive - but temperatures are sufficiently moderate for life to exist in greater abundance and variety than in the centre of the hurricane. Most of this region is water, although there are a few small groups of islands towards the western periphery. Winds in this region are a combination of those generated by the world-hurricane and those of the rest of the atmosphere.
Upgbpr-Wtdu. The hospitable lit regions sunwards of the terminator between the day and night sides of Gu-Pu-Kra. These are the regions outside the world-hurricane which are in daylight. They are the most hospitable regions of Gu-Pu-Kra with moderate weather and temperatures, and thus are home to the greatest density and diversity of life. All of the significant dayside land masses of Gu-Pu-Kra lie within this region. Winds here are largely dominated by the air flow from the night to the day side of Gu-Pu-Kra. However, even though it is the most hospitable region on Gu-Pu-Kra this region is still wracked by frequent major storms spun off by the world-hurricane and its sunward coasts are frequently battered by what, on Earth, would be considered to be freak waves, though on Gu-Pu-Kra they almost normal.
Ueb-Bgt. The terminator. The region where Rp'Gu sits roughly on or is partly hidden by the horizon, and where libration effects cause 'wobbles' in the rotation of Gu-Pu-Kra of some plus or minus 2°. These mean there is a cycle of varying daylight intensity some seven Earth days long. In most of this region this variation is due to varying fractions of Rp'Gu being above the horizon at different times; only at the extreme night side edge of this region does Rp'Gu actually set, giving periods of true night. This region is the second most hospitable on Gu-Pu-Kra, and so has diverse and plentiful life. Because of the large size of Rp'Gu in the sky of Gu-Pu-Kra, and atmospheric refraction bending the light of Rp'Gu into the nominal night side, this region is some 7.7° deep [the same as the width of Rp'Gu in the sky] but offset by 1.4° or so towards the night side, so that it covers some 6.7% of the surface of the planet, with daylight - as in any part of Rp'Gu being visible above the horizon - extending up to some 5.2° into the nominal night side.
Ugodugg. The twilight zone. These are the regions of Gu-Pu-Kra where Rp'Gu itself is never visible, but which are illuminated to differing degrees by the scattering of its light from the atmosphere of Gu-Pu-Kra so that it is in permanent twilight. Because of the thick atmosphere of Gu-Pu-Kra this region extends some 44° into the nominal dark side from the edge of the Ueb-Bgt region, becoming progressively darker and colder the further into the night side one travels. This means that roughly 76% of the nominal night side [and so roughly 88% of the total surface of Gu-Pu-Kra] actually sees at least some daylight, even if only at low levels. The level of light in Ugodugg allows photosynthesis to occur to some extent in the parts of it close to the terminator, but in most of Ugodugg light levels are too low for this to be effective. Despite its lack of light the twilight zone still has abundant life, in particular around the many active volcanic regions that dot its surface. Many of these obtain energy from chemosynthesis of the chemicals emitted by them. Others gain energy from the temperature differences between the heat of the volcanic regions and the cold of the general dark side environment via a process of thermosynthesis, or from a mixture of this and chemosynthesis.
O-Ugrpdwt. The dark zone. These are the parts of Gu-Pu-Kra that never see any daylight; because of light being bent and scattered by the atmosphere of Gu-Pu-Kra this region actually begins some 49° into the nominal night side and so covers only some 12% of the surface of Gu-Pu-Kra. Always dark, these regions become progressively colder the further from the terminator one goes. In the centre of the night side is a region of huge downdrafts where cold air falls from the high atmosphere back to surface and begins to re-circulate back to the day side. Like the twilight zone, the dark zone still has abundant life [at least compared to the arctic regions of the Earth] powered by chemo- and/or thermosynthesis and adapted to the deep cold and dark there.

THE SKY OF GU-PU-KRA

The atmosphere of Gu-Pu-Kra has some 220% of the thickness of that of the Earth, and in addition to this contains far more dust than that of Earth, due to both the thickness of the air allowing dust to float for longer and the greater volcanic activity of Gu-Pu-Kra compared to that of the Earth. As such it scatters light [the effect that makes the sky blue on Earth] more than the Earths atmosphere does. However, the lack of blue light from Rp'Gu means that the sky of Gu-Pu-Kra is not blue. Instead it is a whitish-pink in colour, shading to brighter and redder around Rp'Gu [that is, sunset colours] and darker away from it. In those regions of Gu-Pu-Kra where Rp'Gu hangs near the horizon there is a permanent, vast and intense red sunset, which is only enhanced by the area of Rp'Gu in the sky being some 225 times greater than that of the Sun on Earth, with, in the opposite direction, a sky that fades to a pinkish-black in colour.

In addition to this, the thick atmosphere of Gu-Pu-Kra leads to greatly increased atmospheric refraction [bending] of the light of Rp'Gu compared to the light of the Sun on Earth. On Earth, atmospheric refraction means than when sunset actually occurs the Sun is physically more than one diameter below the horizon. Likewise, atmospheric refraction causes the zone of twilight that extends to the point where the Sun is physically some 18° below the horizon. Because of its thick atmosphere, refraction by it on Gu-Pu-Kra is some 245% as strong as that on Earth so that the twilight zone extends some 44° into the nominal dark side of Gu-Pu-Kra.

THE LIFE FORMS OF GU-PU-KRA

As far as can be ascertained, life on Gu-Pu-Kra originated in much the way as it is speculated that it did on Earth, around oceanic hydrothermal vents. As these were (and remain) more common on Gu-Pu-Kra than on Earth, life evolved somewhat sooner and in more locations than it did on Earth, so that it began, and remains, somewhat more diverse than Earthly life.

Within the first 1.2 billion Earth years of its life Rp'Gu was subject to violent flares. The ultraviolet radiation emitted by these helped to drive the early evolution of life on Gu-Pu-Kra to the point that when the flares died down as Rp'Gu matured, life was sufficiently diverse for evolution to progress without it, driven only by the many other environmental pressures existing on the planet.

[Note that the Earth as a whole was an anaerobic environment for at least the first 3.65 billion years of its existence, before photosynthetic organisms changed the atmosphere into its present aerobic form.]

Like life on Earth, life on Gu-Pu-Kra began as anaerobic, surviving without oxygen, and like it lived in an environment where there was plentiful light energy. This drove the evolution of the process of photosynthesis among the Gu-Pu-Kraian equivalent of plants. However, the photons emitted by Rp'Gu are, on average, of a much lower energy than those of the Sun. As such, when photosynthesis evolved on Gu-Pu-Kra it developed in a different way to that on Earth. The most significant difference between it and photosynthesising life on Earth is that photosynthesis on Gu-Pu-Kra did not generate oxygen [as is the case with some photosynthetic bacteria on Earth]. This has meant that since then, although more complex and advanced life has developed, it has remained anaerobic, using chemicals other than oxygen to allow it to release energy.

Because there are no seasons on Gu-Pu-Kra, plant and animal reproduction tends to occur at a roughly constant level over time, with no synchronisation to any environmental cues, so that there are no mating seasons and so on.

Because of the permanent darkness on the dark side of Gu-Pu-Kra, and the fact that its oceans become dark at a much shallower depth than those on Earth [due to the much redder light of Rp'Gu compared to the sun, which does not penetrate the water as well], the use of bioluminescence for signalling and display is much more common among the life forms of Gu-Pu-Kra than it is among those of the Earth. This is one of the few places where blue light can be seen there.

THE GUBPRWUFU

In body plan the Gubprwufu are quadrupedal, with a relatively long, flexible body. Their legs have two knees, which on both pairs of legs have backward bending upper knees and forward bending lower ones. As creatures descended from the bilateral animals whose third limbs in each ring was under the body, at the rear underside of the body between the rear legs is a thin three-jointed limb. This is used for swatting flies, signalling body language and so on, much like the tails of Earth animals.

Their feet are a cloven hoof-like structure split into two halves. The underside of the foot has layers of keratin-like material tapering backward to the rear of the foot giving a sort of tapering chevron shape of hard ridges with softer flesh between [this gives them odd footprints from a human perspective]. Their feet do not work terribly well on hard artificial surfaces so they tend not to use them. When they have no choice, they will wear shoes analogous to horseshoes to protect their feet.

Between the front pair of legs is the third limb of that ring of limbs. Originally it was a flat fringe-edged boned tentacle just capable of creating clicks and snaps (like human finger clicks) but in time it has evolved move complex structures as well as longer 'fingers', chambers of various sizes and other structures that can be compressed and popped to create pops, clicks, burp noises and so on that are modulated and combined for speech. This speaking limb now looks like a sort of odd 'bubble bush' hanging under each individual Gubprwufu.

Down the centre of their back runs a long hump, pierced by many hundreds of small openings, which forms a hive-home for the Eb'P [Muninns] associated with that particular Gubprwufu. Along with their other benefits, their symbiotic Eb'P hives provide warmth to their hosts to help them remain active in cold climates [much as bee hives generate warmth on Earth].

In front of the forelegs the body narrows and rises into a thick neck which bulges to house the Gubprwufu brain before trifurcating into the three long, flexible tentacles which form the Gubprwufu manipulative limbs. One of these extends from the bottom of the neck while the others extend from the top of each side. Their tentacles split into two 'fingers' roughly eighty percent of the way towards the tip. The two 'fingers' can work in opposition to one another to give a high degree of manual dexterity.

In cross-section the Gubprwufu tentacles have a flat inner side and a roughly half-elliptical cross-section. The entire inside faces of the tentacles have prehensile ridges perpendicular to their length, which are thicker and more widely spaced towards their bases, and thinner and more delicate towards the tip. These can lift front-to-back and ripple along their length (that is, across the width of the tentacle) to give improved manipulative ability. Their foot ridge structure is based on the same overall pattern, but modified for walking.

Individual Gubprwufu have a 'handedness' in that at birth they tend to favour one of their three tentacles for manipulation and so on, with an equal percentage preferring each. However, the sharing of memories with others of all three handedness's tends to override this innate preference so that all adult Gubprwufu tend to be essentially ambidextrous.

Within the three tentacles is the Gubprwufu's mouth, a treble beak formed of a keratin-like material which is worn down at the edges by eating, but which grows constantly from the body. Inside the mouth they have three quite long tongues.

Behind the places where the tentacles join the head and neck are three clusters of small, simple protuberant eyes which see reds and infra-reds [similar to those of other animals on Gu-Pu-Kra]. Two face up and to the side, the third faces down; this downward facing cluster is fully functional, and provides information on the ground below as well as vision when the head is down, for example when drinking. Altogether, the three eye clusters give 'binocular' vision [in the sense of having depth perception] very nearly spherically around the body.

The number of eyes in the eye clusters of each individual Gubprwufu varies between individuals, and also between eye clusters on the same individual. This arrangement is generally unique to an individual and is a means of fairly unambiguous identification among them. They blink by eye retraction, like frogs, normally in 'waves' across each eye cluster.

In addition to the main eye clusters there are an additional six almost-vestigial eye clusters on the joints of the legs, 'tail' and speaking limb. Much smaller, these clusters cannot see as such, but they can detect differences in light levels.

Between the manipulative tentacles are three clusters of alternating backward and forward pointing bristle-like structures. These help distribute DNA-carrying honey-like saliva from the salivary glands to the exterior of the body where it can be accessed by the Eb'P, and also allow DNA deposited by the Eb'P to travel back to the mouth where it can be taken in and read.

On each side of the neck where it joins there body there is the flat diaphragm of an ear, which gives them reasonably good hearing. Note that because of the thicker atmosphere of Gu-Pu-Kra their hearing is not as sensitive as that of (for example) and equivalent Earth creature.

In terms of size, individual Gubprwufu are larger than humans, with an average mass of some 220 kilograms [as opposed to an average human mass of some 65 kilos, averaging over men and women; this is roughly the same as a pony]. They are somewhat stronger and more muscular than an Earth animal of the same size due to the somewhat heavier gravity of Gu-Pu-Kra.

In terms of colour, to human eyes the Gubprwufu are a dark khaki colour, much the same as the photosynthetic vegetation of Gu-Pu-Kra. The is normally even in colour, but some individuals have mottlings or other colour variations, and populations from different regions may also have differences in colour and, sometimes, patternings.

Internally, their bone structure is like that of other animals on Gu-Pu-Kra, being based on a structure not unlike a stack of three-pointed bony stars running down the length of the body. The size of the stars and the length of their 'rays' vary depending on the location in the body; long and strong rays are found in particular at the limb joints, where the weight of the body is supported. Elsewhere the rays are smaller, though the size of the 'core' of the star tends to remain similar, for strength. Under the skin, an interlocking mesh of 'scales' provides some degree of protection from damage. Particularly large and strong versions of these provide protection for the brain and other vital organs. They have two hearts, one each for the forward and rear halves of the body.

As with other animals on Gu-Pu-Kra, the Gubprwufu brain developed from simpler nerve structures concerned with limb and sense organ control and functionality. In the Gubprwufu the brain in which their sentience resides is in the head, but there are secondary brains at each of the other two rings of limbs. The one at the forelegs is actually quite large as it holds the speech centre used to provide the complex control required for the speaking limb. As part of this there is a thick nerve trunk between the main brain and this secondary centre to effectively control their speaking.

Like other land animals on Gu-Pu-Kra, the Gubprwufu do not have lungs. Instead, their interior is divided between a nitrate extraction system, nitrate storage, and a digestive system analogous to that of Earth animals. Both nitrate and energy-bearing food is eaten through the mouth, and the waste products from both are excreted through an equivalent of an anus at the rear of the body. Respiratory waste is excreted as solids along with digestive waste.

Also like the other animals of Gu-Pu-Kra, the Gubprwufu are ectothermic [cold-blooded], although because of their size they also have a degree of gigantothermy [where large, bulky ectothermic animals are more easily able to maintain a constant, relatively high body temperature than smaller animals by virtue of their greater volume-to-surface area ratio]. Despite this they are as active as human, their cold-bloodedness not necessarily implying that they are slow or have slow reactions.

The Gubprwufu evolved in the most hospitable and biologically diverse part of Gu-Pu-Kra. These regions can support a fairly high population of Gubprwufu due to their cold-bloodedness, which means that require less food and so on than an equivalent population of warm-blooded creatures.

GUBPRWUFU REPRODUCTION

As with the other animals of Gu-Pu-Kra the Gubprwufu have no breeding season. Also like the other land animals of Gu-Pu-Kra, the Gubprwufu exchange DNA [have sex] via their mouths rather than any other part of their bodies. Fertilised eggs are swallowed by one or other of the mating pair.

Each egg then hatches in the stomach of its parent and the resultant young then grows as a tapeworm-like parasite in the gut of the parent until they are large enough to survive in the outside world.

All adult Gubprwufu constantly produce special DNA packs that are then swallowed by them. Most of the time these packs are not used, and are simply re-digested and absorbed. However, when they encounter a foetus they are taken in by it. These DNA packages 'program' the foetus with certain types of behaviour, for example how to walk and talk, that allows them to know how to do so as soon as they are born, and so helps them to survive. [Some animals which do this have parasites and other associated species that also learn from them via these special DNA packages, even to the point of speech in some cases.] As such they are born sentient and able to talk and contribute.

When the young are ready to be born they begin to secrete a laxative substance that makes their parents excrete them [lovely!]. Following this they are cared for by adults, normally (but not always) their parents.

Due to the way their limbs are arranged, young Gubprwufu are born head-first. They initially have a somewhat different form to the adults, being long and thin with relatively short gripping limbs for holding on internally. Once they are born they use the same limbs to hold onto parents externally while they grow further and learn more via DNA transfer young Gubprwufu are programmed, not taught. As part of this the body thickens, the legs lengthen, they grow a Eb'P [Muninn] 'hive', acquire Eb'P, and so on, all relatively quickly after birth, certainly much faster than is the case with humans. [This does not quite count as metamorphosis as the change is not step-like but instead gradually and involving a reshaping of their proportions.]

On the birth of a child all Gubprwufu in the vicinity lose a fraction of their 'bees' as they are attracted by pheromones to colonise the new 'hive' in the new individual. All Gubprwufu hives have sufficient slack in their population numbers that this temporary depletion of Eb'P numbers is normally entirely bearable.

As a side effect of the way in which either gender can brood young, there is no physical sexual dimorphism among the Gubprwufu; both genders are on average the same size, same strength and so on. However, there are some non-functional differences in appearance between the genders, which allow members of the species to distinguish between each other. Because of their exchanging of memories they also lack any kind of mental sexual dimorphism."
