Pensaspidus

## Pensaspidus jellyfishmonii

Status: CR

Temporal Range: R.106 - Present (Novaglacian)

Habitat: Temperate Shallows, Polar Shallows, Temperate Open Ocean, Polar Open Ocean

Distribution: Southern Hemisphere

Niche: Predator

Size: 7.5cm (length)

Nutritional Worth: 59.5/10 x 7.5 = 44.6

Predecessor: Arthroskulus pelagus

Classification: Roharasrinae (sf), Codowecoiidae (f), Probocephala (o), Cylindrea ©, Bilateria §

Perception: Blurry vision with no depth perception on either side, blurry front vision with depth perception.

Latest Mutations: Mandibles = 4, Legs = 3, True Muscles = 4

Info: Swapping a razor-sharp beak for a pair of chitinous mandibles, these species can eat more efficiently than its ancestors as the mandibles allow them to grip prey and also bite in comparison with the inefficient stabbing motion of its forefathers. The mandibles are not particularly sharp or cutting, but it does not need to be for their soft-skinned prey. One advantage that the beaked species have is the actual method of killing, which is generally much easier than the grip and cut method that this species must employ. In a case of unexpected convergent evolution, the circular, hydrostatic muscles that made the lineage so worm-like have developed into traditionally, both in structure and in placement. When their body moves, it goes from side to side, like other animals with similar muscles, although internally they have fundamental differences. It lives alongside Arthroskulus, and both compete for the same food.

Description: The top of the blue, cylindrical body is protected by a tough exoskeleton made out of chitin, which has extended to form a pair of mandibles around the mouth at the end of a proboscis. Some of the armour has also formed a fan-shaped tail protruding from the rear, which can be moved up and down by muscle and a muscular siphon at the rear propels out water. The armour behind the head contains a spiracle on each side, allowing oxygen through it. There are four pinhole eyes below the armour, but none of them look up; two are at the front, and two are on the sides. Inside their body, they have a simple gut leading to an anus, a stomach containing digestive carnivorous bacteria, a nerve network and small bunch of ganglia, and an open circulatory system filled with blue-green hemacoel. There is also a swim bladder, unconnected to the gut. Anti-freeze proteins flow through the hemacoel. The body is adapted to only low to quite high salinities.

## Pensaspidus tardasanguisensis

Temporal Range: R.113 - R.122 (Novaglacian Stage of the Atroxian)

Habitat: Temperate Shallows, Polar Shallows, Temperate Upper Ocean, Polar Upper Ocean

Distribution: Southern Hemisphere

Niche: Predator

Size: 8cm (length)

Nutritional Worth: 59/10 x 8 = 47.2NP

Predecessor: Pensaspidus jellyfishmonii

Classification: Roharasrinae (sf), Codowecoiidae (f), Probocephala (o), Cylindrea (c), Bilateria (p)

Perception: Blurry vision with no depth perception on either side, blurry front vision with depth perception.

Latest Mutations: Genders = 6, Stronger Mandibles = 3, Closed Circulatory System = 2

Info: Pensaspidus tardasanguisensis was a small, fairly uncommon predator living in shallow ocean and seas of the Southern Hemisphere, except in the tropics. This species is set apart from its relatives by having genders, which boosted the genetic fitness of the species, but it also meant they produced less offspring. However, once a Pensaspidus tardasanguisensis reached a mature adult age it transformed into a hermaphrodite, giving it a better chance at reproducing before it dies. Pensaspidus tardasanguisensis also have open circulatory system that have wider blood vessels and hemacoels and lower pressure; this resulted in a less efficient system and lower stamina. With these problems and a lot of competition in the niche, its population numbers were never very high. It struggled on until extinction.

Anatomy: The top of the blue, cylindrical body is protected by a tough exoskeleton made out of chitin, which has extended to form a pair of mandibles around the mouth at the end of a proboscis. Some of the armour has also formed a fan-shaped tail protruding from the rear, which can be moved up and down by muscle and a muscular siphon at the rear propels out water. The armour behind the head contains a spiracle on each side, allowing oxygen through it. There are four pinhole eyes below the armour, but none of them look up; two are at the front, and two are on the sides. Inside their body, they have a simple gut leading to an anus, a stomach containing digestive carnivorous bacteria, a nerve network and small bunch of ganglia, and an open circulatory system filled with blue blood that travels through wide, low pressure vessels into enlarged hemacoels. There is also a swim bladder, unconnected to the gut. Anti-freeze proteins flow through the hemacoel. The body is adapted to only low to quite high salinities. Males, females and hermaphrodites are virtually identical.

Behaviour: This species is capable of processing information gathered from sense receptors and using that to form a picture of its surroundings. It can then respond to stimuli. It also has basic reasoning.

Cause of Extinction: Outcompeted

## Pensaspidus aquadulciensis

Status: EN

Temporal Range: R.127 - Present (Novaglacian)

Habitat: Tropical Rainforest, Tropical Monsoon Forest, Savannah, Hot Steppe, Subtropical Desert, Chaparral, Temperate Forest, Taiga Estuaries

Distribution: Tartarus

Niche: Predator

Size: 7.5cm (length)

Nutritional Worth: (69.5/10 X 7.5 =) 52.1NP

Predecessor: Pensaspidus jellyfishmonii

Classification: Roharasrinae (sf), Codowecoiidae (f), Probocephala (o), Cylindrea (c), Bilateria (p)

Perception: Blurry vision with no depth perception on either side, blurry front vision with depth perception.

Latest Mutations: Brackish Tolerance, Freshwater Tolerance

Info: Seeking refuge from ocean predators, this Pensaspidus species has moved into the relatively calm waters of the estuaries, where there is ample prey and no predators to face. They live only in estuaries due to that being where their prey is, but they can tolerate freshwater too.
