Nothokossyphus

## Nothokossyphus elegans

Latest Mutations: More Eggs, Pump Vessel

This is a simplistic, eel-shaped filter-feeder. In addition to swimming through rivers and lakes of Ithaca filtering, it can weirdly absorb meat through it's skin, so many can be seen laying on large corpses. At the time of it's appearance, it has no natural predators. It lays double the eggs it's predecessor laid and also has a pump vessel that helps it keep the blood flow up around the open circulatory system.

Status: Unlisted

Stats: Buoyancy 1 (Adjustable Buoyancy). Coordination 2. Digestion 2 (100% Meat, Digests 70%). Immunity 2. Filtration 1 (7/4 = 1.8x1 = 1.8). Respiration 2 (Stationary Ventilation, Ram Ventilation, 10% off). Stamina 4. Strength 2. Swim Agility 2. Swim Speed 0.3. Support 1. Toughness 0 (1 - spine). UV Resistance 2. Walk Agility 1. Walk Speed 0.7.

Intelligence / Behaviour: Intelligence / Behaviour: 1. Hungry > Search for food. 2. Food > Filter with mouth or absorb through skin. 3. Tired > Rest. 4. Pain > Swim away. 5. Maturity > Reproduce.

External Features: The tapering body has skin containing food-absorbing proteins and  blue melanin pigments and starts with a mouth surrounded by chemoreceptors receptors. On top of the head is a pair of cup eyes and three gill slits sit behind the head. There is a line of electroreceptors along the body, where there is also a pair of pectoral ray-fins.

Internal Features: Each cell in the body contains a relatively small number of piezolytes. It has a hemacoel and dorsal pump vessel that circulates blood, red because of hemoglobin, as well as a system of muscles. Near the lower wall can be found the gonads as well as the large protonephridium and near the upper wall is the oily swim bladder. Through the mostly lower half runs the monogastric digestive system, from the mouth through the tubes to the stomach and intestines. Ganglia in the head connect to a single nerve cord along the dorsal half, which has many nerves branching off it to encompass the whole body. A cartilage vertebra runs along the back.

Reproduction: Sexual Reproduction. External Fertilisation. 2,000 eggs per spawn.

Castes/Phases: None.

Locomotion: Active (20NP). Moves body side to side in an anguillaform motion (+1 Stamina).
