Procrinus

## Procrinus primus

Latest Mutations: Larvae, Stalk, Bigger

This species appears a bit like a crinoid. It has a crown of arms covered in feather-like pinnules which are lined with tube feet, which makes it a good filter-feeder. A hard theca protects the head and the body has an endoskeleton of ossicles.  It retains the swimming adaptations like the jellyfish-bell below the theca and the lines of cilia on membranes along the body. This is despite having a root-like holdfast, which it can use to attach itself to sediment. It lives throughout the upper 500m of the northern hemisphere temperate Uteenessa ocean.

Stamina 4. Strength 1. Support 1. Swim Speed 0.5. Toughness 3. Viscosity 1. UV Resistance 1. Walk Speed 1.5.

Intelligence / Behaviour: 1. Hungry > Wait for food. 2. Food > Filter with arms and tube feet. 3. Tired > Rest. 4. Pain > Swim away. 5. Maturity > Reproduce.

External Features: The cylindrical body has yellow skin. There is an endoskeleton of ossicles and they are arranged in plates in a up around the front called a theca. At the front are arms lined with feather-like pinnules lined with tube feet, followed by the circular mouth and chemoreceptors. It has teeth in it's mouth. There are six pairs of gill slits. The rest of the body is composed of a stalk made of a column of ossicles and at the bottom is a root-like holdfast.

Internal Features: Each cell contains lysozymes and piezolytes. A water vascular system carries water from the tube feet to the main canals that radiate from the central canal around the mouth, and also from the madroporite. The body has a hemacoel and a few small blood vessels from the gills. 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 with a nearby notochord.

Reproduction: Sexual Reproduction. External Fertilisation. 1,000 eggs per spawning.

Castes/Phases: Larval Phase until 5% developed: Larval C: have a jelly-filled dome, have four membranes with lines of cilia, a pinhole eye on the ventral side but no stalk or holdfast.
