Pteryphysis

## Pteryphysis volanus

Latest Mutations: Move fins, Smaller, Bladder

Status: Extinct (Samadaran GRB)

Habitat: Temperate Shallows, Temperate Upper Ocean

Niche: Herbivore

Size: 2.5cm (length)

Nutritional Need: (143NP/10) x (2.5/10) = 3.6NP

Food / Oxygen Requirement: (3.6 x 0.6) x 0.9 = 1.9NP / 3.2NP

Abilities: Anti-Freeze. Circulation, Small Body. Excretion, Liquid. Excretion, Solid. Permeable Skin. Pressure Tolerance, Low. Urine Storage. UV Resistance, Moderate.

Perception: Chemoreception 2 (Senses chemicals 5m away). Sight 1 (clear sight to the sides).

Stats: Coordination 1. Digestion 2 (can break down multicellular matter, 10% off). Filtration 2. Immunity 1. Intelligence 1. Respiration 2 (Cutaneous Respiration, Ram Ventilation, 10% off). Stamina 2. Strength 1. Support 1. Toughness 3. Viscosity 1. Swim Speed 0.5. Walk Speed 0.2.

Intelligence / Behaviour: Processes information and responds based on fixed behaviours. When observing a predator; swim away. When hungry; sense for food. When ready to reproduce, sense for other adults and move towards them, then attempt to mate with the source.

External Features: It has a cylindrical body covered almost completely covered on the back by a calcium carbonate shell secreted by the mantle, with red pigmentation in the skin. A mouth with chemoreceptors and two cirri along with a pair of stalks with an eye on each side are on the head. Two pectoral fins protrude through slits in the shell. There are mucus glands on the underside of the muscular foot which takes up the ventral side.

Internal Features: Inside each cell has a low pressure tolerant metabolism. Three gill slits sit each side of the head. Anti-freeze glycoproteins flow in the body fluids. There is a space in the shell for the body to retreat into. Muscles line each side of the body. The gastrointestinal tract from the mouth has a stomach with digestive juices followed by intestines, with vegetation-digesting microfauna, leading to the anus. A brain encased in head connects to two nerve cords which branches into a network of nerves, with a notochord running alongside. It hosts both male and female gonads. The hemacoel cavity, open circulatory system has violet blood containing hemerythrin and anti-freeze proteins. The nephridium expels waste into the bladder.

Reproduction: Sexual, Ovuliparity (External Fertilisation). 1,000 eggs.

Castes/Phases: None.

Locomotion: Wave Motion. Pectoral Fin Flapping. Active (20NP).
