Archaiapasaria

## Archaiapasaria westenrai

Status: CR

Timespan: R.71 - Present

Habitat: Lake, River

Distribution: Northern Hemisphere Temperate Rivers & Lakes

Niche: Herbivore

Nutritional Value: 85.8

Size: 12cm (Length)

Predecessor: Petrocoilius rivieri

Classification: Archaiapasaridae, Makouridea, Caudaria

Latest Mutations: Lobe Fins = 3, Tail Fins = 4, Fish Shape = 5, Swim Bladder = 4

Info: This Eztan animal is the first to be recognisable as being similar to a fish; the only thing that is really preventing this distinction is that it lacks pectoral fins. It is much more suited to swimming about than its relatives, which had to return to the seafloor to rest, and it's efficient shape and tail fins make it much faster too. It is very common in the temperate rivers and lakes of the northern hemisphere. It feeds on local seamosses growing below the surface. In the loss of it's long tail, this species has become shorter than its predecessors but it is has a similar overall mass owing to its broader shape. Furthermore, the stiffer, albeit more powerful, bodily movements of the tail that propel the animal through the water, reduce the effectiveness of wielding tail spikes.

Description: It has a stout, orange and red, stream-lined body, like the shape of a fish and a short tail with a tail fin above and below the tail. These are shaped like horizontal semi-circles and together make a circle; they are supported by rays of cartilage. Two poisonous spikes protrude to the side of the tail. The front of the body has a cartilage jaw, and within in it several square teeth. It retains two venomous fangs in the roof of the mouth. On each side of the head is a lens-covered pinhole eye, with muscle that allows them to swivel. Three gills mark the body, which is also lined with unseeable electroreceptors. The mouth leads to a primitive gut and stomach, with weak herbivorous bacteria. The food is ground up in a gizzard first. Centrally located is a sac of gas called a swim bladder, and supporting the body are vertebrae made of bone. Also supporting the body are muscles with special vacuoles and an open circulatory system.

## Archaiapasaria circulus

Temporal Range: R.89 - R.139 (Cinisian to Gammavian Stage of the Atroxian)

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

Distribution: Olympia

Niche: Pelagic Filter-Feeder, Herbivore

Nutritional Value: 78.1NV

Size: 12.5cm (length)

Predecessor: Archaiapasaria westenrai

Classification: Archaiapasarinae (sf), Thanostomidae (f), Flagracauda (so), Caudomorphii (c)

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

Latest Mutations: Closed Circulatory System

Info: This species was a step ahead of its contemporaries, as it had a closed circulatory system. This was much more efficient and means that it had better stamina - and had a better chance of escaping predators. It fed on aquatic moss, phytoplankton and other vegetation matter in the freshwater of the northern hemisphere.

Anatomy: It has a stout, orange and red, stream-lined body, like the shape of a fish , although it has a whip-tail, with a tail fin above and below the base of the tail. These are shaped like horizontal semi-circles and together make a circle; they are supported by rays of cartilage. Two poisonous spikes protrude to the side of the tail. The front of the body has a cartilage jaw, and within in it several square teeth. It retains two venomous fangs in the roof of the mouth. On each side of the head is a lens-covered pinhole eye, with muscle that allows them to swivel. Three gills line the body, which is also lined with electroreceptors. The mouth leads to a primitive gut and stomach, with weak herbivorous bacteria. The food is ground up in a gizzard first, by gastroliths. Centrally located is a sac of gas called a swim bladder, and supporting the body are vertebrae made of bone. Also supporting the body are muscles with special vacuoles and a closed circulatory system.

Predecessor: Archaiapasaria circulus

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

Latest Mutations: Carnivorous Digestive Bacteria, Larger

Info: After millennia on its own in the rivers and lakes of Ezta's continents, the herbivorous Archaiapasaria genus produced a carnivorous species and moved into the niche of predator. At that moment, the only prey around was other Archaiapasaria. Like them, they were very common but were driven extinct by the Gammavian Extinction.

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.
