Icthyotelus

## Icthyotelus sinspica

**Info**

Status: VU

Timespan: R.65 - Present

Habitat: Estuary

Distribution: Cosmopolitan

Niche: Pelagic Filter-Feeder

Nutritional Value: 27.3NV

Size: 7cm (length)

Predecessor: Charitomenchelus etalas

Classification: Icthyotelusidae, Tyrannidea, Caudaria

Latest Mutations: Tail Fins = 2, Fix Pectoral Fins = 5, Freshwater Tolerance = 3

Info: Unlike all it's living relatives and some of its ancestors, the long tail has no spikes. It probably lost them as there was a lack of predators in their range; they live only in temperate estuaries, where the brackish water is just the right balance to suit their rather limited salt intake abilities. Overall, this is a relatively small area to live, but it is the only animal that lives here. The pectoral fins have become smaller, and more streamlined like a ray-finned fish; they are held against the body and composed of a cartilage limb branching off the vertebrae and three supports covered in skin. Muscles in the limb make it move, so this animal is faster than its ancestors.

Description: It has a tapering body, lined with electroreceptors and three gills on each side. It has two pectoral ray-fins and a pair of forward-facing cup eyes on the head. An oily liver helps to maintain buoyancy. An open circulatory system bathes the organs in hemacoel, and the body is controlled by ganglia. Down the back are cartilage vertebrae. In the gut, is a primitive stomach with the ability to digest multicellular matter.

## Icthyotelus olympiusensis

**Info**

Status: NT

Temporal Range: R.148 - Present (Gammavian Stage of the Atroxian)

Habitat: Tropical Rainforest, Savannah, Subtropical Desert, Chaparral,
Temperate Forest, Taiga

Distribution: Freshwater in Olympia

Niche: Pelagic Filter-Feeder

Size: 7cm (length)

Nutritional Worth: (8 x 7 =) 56NP

Predecessor: Icthyotelus sinspica

Classification: Charitomenchelusinae (sf), Charitomenchelusidae (f), Eoicthyes (so), Ouriformes (c)

Perception: Blurry vision with no depth perception on either side, can use electroreception and chemoreception up to ten metres away.

Latest Mutations: Chemoreceptors, Freshwater Tolerance

Info: Across the slowly breaking up continent of Olympia, this Icthyotelus species has become accustomed to freshwater and lives throughout the network of rivers and lakes across the continent. It is also more successful in that in can actively hunt out food with chemoreceptors on the head.

Intelligence / Behaviour: Processes information and responds based on fixed behaviours. It knows to eat and avoid being harmed.

External Features: It has a tapering body with blue pigmentation and a paddle-like caudal fin fused with the long dorsal fin. It also has triangular pectoral ray-fins. The thin skin layer over the body has a line line of electroreceptors along the flank. A mouth and two forward facing cup eyes are on the face, which is also dotted with chemoreceptors.

Internal Features: There are three gill slits each side of the head. The muscles on each side are attached between the body wall and cartilage vertebrae. From the vertebrae, a rib cage curves out and encloses the lower part of the body. The gastrointestinal tract from the mouth has a stomach with digestive juices followed by intestines leading to the anus. The brain is encased in a cartilage skull, which connects to a ring around the mouth. The brain connects to two nerve cords which branch into network of nerves. There is an oil-filled swim bladder in the middle. The hemacoel cavity, an open circulatory system, has red blood containing haemoglobin. It hosts both male and female gonads. Protonephridia, connected to hemacoel, expels waste through pores.

Latest Mutations: Closed Circulatory System - 3, Herbivorous Bacteria - 4, Add teeth like iguana - 3, Carnivorous bacteria - 6

Info: This species can exhibit strange feeding behaviour. Although normally they are found to be gracefully filtering the rivers and lakes of Olympia, they also can digest meat. With no other method to ingest meat, they are forced to drastic measures. Like Earth hagfish, if they come across a corpse, they can absorb the nutrients of it through the skin and gills, without having to use their mouths. However, because they cannot bury into the carcass and there are no large carcasses around very often, this method is used sparingly. They also can digest plants but have no real method of ingesting it.

External Features: It has a tapering body with blue pigmentation and a paddle-like caudal fin fused with the long dorsal fin. It also has triangular pectoral ray-fins. The thin skin layer over the body has a line line of electroreceptors along the flank. Mechanisms in the skin and gills can transfer nutrients directly into the body. A mouth and two forward facing cup eyes are on the face, which is also dotted with chemoreceptors.

Internal Features: There are three gill slits each side of the head. The muscles on each side are attached between the body wall and cartilage vertebrae. The gastrointestinal tract from the mouth has a stomach with carnivorous digestive juices followed by intestines with herbivorous microfauna, leading to the anus.

## Icthyotelus aeaensis

Latest Mutations: Smaller

Shortly before this species appeared, Salcaedis arrived in Aeaea. This arthropod was a much larger animal and a danger to the species as it preyed easily on larger Icthyotelus species. However, this species shrunk until it was no longer of nutritional value to the new predator but it makes them planktonic. Other than that, they lead much the same lives as other members of the species.

## Icthyotelus sensus

Latest Mutations: Smell, Pinhole Eyes

This is yet another new Icthyotelus and this one is the most advanced yet because it has olfactory receptors and pinhole eyes to allow it to smell and see (albeit poorly) respectively. It can therefore track down its food much better and so outcompetes its cousins. It is still a primitive filter-feeder though.

It has a mouth, olfactory receptors and a pair of forward-facing pinhole eyes on the face. Along the length of the body are electroreceptors and there are also two pectoral ray-fins.

Internal Features: Mechanisms in the skin allow it to take nutrients in directly through it. Three gill slits line just behind the head. An open circulatory system allows red blood to diffuse around the body. There is also a nephridium and the body is lined with muscle. Food enters the stomach and then the intestine before exiting the anus. A brain leads to a nerve cord with nerves running off like rungs on a ladder. The nerve cord is supported by a cartilage vertebrae. In the centre of the body is an oily liver and below this are the testes and ova.

## Icthyotelus scanius

Latest Mutations: Smell, Smaller

Many millions of years after the first Icthyotelus evolved, this species evolved from it. It had a better smell - and was slightly smaller - so outcompeted its predecessor in places where it lived; because it could only tolerate brackish water, this was only one estuary in the entire continent of Olympia. Like other Icthyotelus, it was a primitive filter-feeder.
