Ctenella

## Ctenella primus

Latest Mutations: Heart, Temperate Tolerance, Group Together

This is a filter-feeder that forms part of the zooplankton with its incredibly small size. It rows through the viscous water with rows of cilia using a few cirri around the mouth to capture food and push it into the mouth. Unlike its predecessor, it has a heart. It lives in the upper portions of the temperate ocean of the Southern Hemisphere.

Status: Unlisted

Habitat: Subpolar Temperate Ocean, Polar Temperate Ocean

Niche: Zooplankton Filter-Feeder

Size: 2mm (length - from cirri to end)

Nutritional Need: 139 x 0.2/100 = 0.3NP

Food / Oxygen Requirement: 0.3 x 0.25 = 0.08NP per round (Needs to intake 0.08/0.6 = 0.1NP per round)/ 0.3 x 0.9 = 0.3NP

Abilities: Anti-Freeze. Exothermic. Liquid Excretion. Low Pressure Tolerance. Osmoconformer (Quite High Salinity). Permeable Skin. Small-Body Circulation. Solid Digestion. Subzero Metabolism.

Perception: Chemoreception 2 (detects chemicals 5m from mouth). Sight 1 (see blurrily on ventral side, monocular vision). Light Sensing (dorsal side).

Stats: Coordination 2. Digestion 1 (100% Meat, Digests 60%). Filtration 2. Immunity 2. Respiration 2 (Stationary Respiration, Cutaneous Respiration, Ram Ventilation, 10% off). Stamina 4. Strength 1. Support 1. Swim Speed 1.5. Swim Stability 2. UV Resistance 2. Walk Speed 0.5.

Intelligence / Behaviour: 1. Hungry > Search for food. 2. Food > Filter with cirri. 3. Tired > Rest. 4. Pain > Swim away. 5. Maturity > Reproduce. 6. Other member of species > go towards.

External Features: The cylindrical body is mostly transparent except for the organs and head, which is blue. At the front are cirri, followed by the circular mouth and chemoreceptors. There are six pairs of gill slits. Along the body are four membranes with lines of cilia on them. On the ventral side of the body is a pinhole eye and on the dorsal side is an eyespot.

Internal Features: Each cell contains lysozymes and piezolytes. The body has a hemacoel pumped by a dorsal vessel and a few small blood vessels from the gills and saccate metanephridium. The blood is violet because it contains hemerythrin. Anti-freeze threitol sugar alcohol flows around the body. It has a gonads. It has muscles across the body. It has a monogastric digestive system. From the ganglia in head is a single, ventral nerve cord with nerves running off.

## Ctenella nocturnus

Latest Mutations: Retreat to Depths During Daylight

Only at night does this simple, tiny filter-feeder rise from the depths in large groups to filter-feed close to the surface. This is probably to avoid predators.
