## Cilistoma primus

**Info**

Status: Extinct (Samadaran GRB)

Temporal Range: R.150 - R.244 (Samadaran Stage of the Oliverian)

Habitat: Tropical Rainforest, Savannah, Subtropical Desert, Chapparal, Temperate Forest

Distribution: Tartarus

Niche: Sessile Filter-Feeder

Size: 2.5cm (length)

Nutritional Worth:

Predecessor: Masticephalus recentibus

Classification: Ciliastominae (sf), Pictolexipotusidae (f), Tunicaphora (o), Violetamata (c), Bilateria (p)

Perception: Can sense chemicals from 10s of metres away, has acute chemical sensing, and has blurry eyesight in one direction with no depth perception.

Latest Mutations: Calcium Carbonate Shell, Cillia Mouth

Info: This group of shelled animals is similar to the older Ostracodermids, but only distantly related. They have evolved in freshwater and have gained calcium carbonate shells to defend against the rise in predators. Some of the cillia from their flanks have migrated to the mouth, where they cause water to flow in with food.

Intelligence / Behaviour: Processes information and responds based on fixed behaviours. It knows to eat and avoid being harmed.

External Features: It has cylindrical body but with an umbrella-shaped top with yellow pigmentation and four fleshy membranes, each lined with thousands of cillia. These are all contained within two asymmetrical valves of a calcium carbonate shell. It has a thin skin layer. A toothless mouth with chemoreceptors around it and on surrounding tendrils, with a single pinhole eye. The mouth contains a ring of beating cillia.

Internal Features: Each cell contains lysozymes in addition to enzymes. Six gill slits line each side of the head. Muscles run down each side of the body. The gastrointestinal tract from the mouth has a stomach with digestive juices followed by intestines leading to the anus. A brain encased in head connects to one nerve cord which branches into a network of nerves, with a notochord running alongside. It hosts male and female gonads. The hemacoel cavity, open circulatory system has violet blood containing hemerythrin and anti-freeze proteins. Protonephridia, connected to hemacoel, expels waste through pores.

## Cilistoma caecus

Latest Mutations: Timed Breeding, Lose Eye in Adults

Inside the shell of an adult, the animal has no need for eyes and so Cilistoma caecus has lost it to become more efficient. The eye remains in the increasingly different larvae form. They also have synchronised their gamete release with the full moon in Early Spring to increase the chances of meeting the gametes of others. Cilistoma lives inside a bivalved shell and sticks its ciliated cirri out to filter food from the river water.

Cilistoma lazlowi evolved from Cilistoma caecus. It's a freshwater Ciliastomid bivalve, using cirri covered in cilia to filter in food. Few species can get through its hard shell.

## Cilistoma cummingsi

Latest Mutations: Freshwater

This was a very primitive yellow, freshwater bivalve that lived only in the intermittent waters of Aeaea. It had no natural predators and filtered passing particles of food with it's tentacles to feed.

Status: Extinct (Samadaran GRB)

Habitat: Brackish Water and Freshwater in Subtropical Winter Semi-Arid Barrens, Subtropical Arid Barrens

Niche: Sessile Filter-Feeder

Diet: Any particle of marine snow meat or organism 0.5mm big or smaller.

Size: 2.3cm (length - shell front to back)

Nutritional Need: 137 x 2.3/100 = 3.2NP.

Food / Oxygen Requirement: 3.2 x 0.25 = 0.8NP per round (Needs to intake 0.8/0.6 = 1.3NP per round)/ 3.2 x 0.9 = 2.9NP

Abilities: Adjustable Buoyancy. Anti-Freeze. Exothermic. Inflexible. Liquid Excretion. Osmoregulation (Brackish Salinity). Permeable Skin. Small-Body Circulation. Solid Excretion. Subzero Metabolism.

Perception: Chemoreception 1 (detects chemicals 1m from mouth). Sight 1 (blurry sight in one direction, Monocular Vision). Light Sensing (other side).

Stats: Buoyancy 0. Clam Strength 1. Coordination 2. Desiccation Resistance 1. Digestion 1 (100% Meat, Digests 60%). Filtration 3. Immunity 2.  Respiration 2 (10% off, Cutaneous Respiration, Stationary Respiration). Stamina 3. Strength 1. Support 2. Swim Agility -1. Swim Speed 0.5. Swim Stability 2. Toughness 3. UV Resistance 2. Walk Speed -0.5.

Intelligence / Behaviour: 1. Hungry > Wait for food. 2. Food > Stick cirri out of shell and filter. 3. Tired > Rest. 4. Pain > Close shell. 5. Maturity > Release gametes.

External Features: The yellow irridiphore-pigmented and cylindrical body is contained within an aragonite, horizontal, symmetrical bivalve shell secreted by the mantle. Around the mouth are ciliated cirri and a circle of chemoreceptors, with a jelly-filled lobe fringing the head. Four ciliated membranes of skin run down the body as do six pairs of gill slits. On one side of the body is an eyespot and on the other a pinhole eye.

Internal Features: Each cell in the body contains lysozymes and a small number of piezolytes. A system of muscles stretches across the body. Near the lower wall can be found the gonads as well as the large saccate metanephridium. 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 ventral half, which has many nerves branching off it to encompass the whole body. Next to this is a notochord. In the middle of the body is a hemacoel with violet (hemerythrin) blood through which an anti-freeze (thrietol sugar alcohol) flows.

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

Castes/Phases: Hermaphroditism.

Locomotion: Sessile (0NP).
