Neoicthyotelus

## Neoicthyotelus ithaca

Latest Mutations: Closed Circulatory System, Odour Receptors

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.

Niche: Benthic Filter-Feeder

Size: 7cm (length)

Nutritional Need: (125NP/10) x 7/10 = 8.8NP

Food / Oxygen Requirement: (8.8 x 0.6) x 0.9 = 4.8NP /8.8 x 0.9 = 7.9NP

Intelligence / Behaviour: Processes information and responds based on fixed behaviours. When feeling pain; swim away. When hungry; filter the water. When ready to reproduce, sense for electrical signals of other adults and move towards them, then attempt to mate with the source.

External Features: The tapering body is covered in iridiphore pigments which give it a metallic blue sheen over the soft, permeable skin. It has a mouth, odour receptors, and a pair of forward-facing cup eyes on the face. Along the length of the body are electroreceptors and there are also two pectoral ray-fins.

Internal Features: Three gill slits line just behind the head. A circuit of closed blood vessels transports red blood 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.

## Neoichthyoskulus aquadulcisus

Latest Mutations: Freshwater Tolerance

Neoicthyotelus aquadulcisus is a simplistic, eel-shaped filter-feeder. It is much like its ancestor only it resides in freshwater rather than brackish, meaning it has a much larger range than its predecessor which is known from only one estuary in Ithaca. This species lives throughout the whole of the continent.

Status: Unlisted

Habitat: Freshwater in Subpolar Oceanic Warm Temperate Summer Semi-Arid Barrens, Polar Oceanic Cool Temperate Humid Barrens, Polar Continental Cool Winter Semi-Humid Barrens

Niche: Filter-Feeder

Diet: Any fresh meat it can get.

Size: 7cm (length - head to tail)

Nutritional Need: 145 x 7/100 = 10.2NP

Food / Oxygen Requirement: 10.2 x 0.25 = 2.6NP per round (Needs to intake 2.6/0.7 = 3.7NP per round)/ 10.2 x 0.9 = 9.2NP

Abilities: Exothermic. Large-Body Circulation. Liquid Excretion. Low Pressure Tolerance. Osmoregulation (Freshwater). Permeable Skin. Solid Excretion.

Perception: Smell 2 (Senses smells 5m away from head). Electroreception 1 (detects movement at sides). Can sense direction of light from head.

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 3. Strength 2. Swim Agility 2. Swim Speed 0.3. Support 1. Toughness 0 (1 - spine). UV Resistance 2. Walk Agility 1.

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

External Features: The tapering body has skin containing blue melanin pigments and starts with a mouth surrounded by olfactory 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. Throughout the body is a network of blood vessels, 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.

## Neoichthyoskulus cadavercolus

Latest Mutations: Absorbent Skin

Neoicthyotelus aquadulcisus 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.
