Ostrapodia

## Ostrapodia ostrapodia

**Info**

Status: Extinct (Samadaran GRB)

Temporal Range: R.140 - R.244 (Gammavian Stage of the Atroxian to the Samadaran Stage of the Oliverian)

Habitat: Temperate Shallows, Temperate Upper Ocean

Distribution: Northern Hemisphere

Niche: Benthic Filter-Feeder

Size: 4cm (length)

Nutritional Worth:

Predecessor: Asposomus cirrus

Classification: Asposomusinae (sf), Ostracodermidae (f), Colyphora (o), Violymphia (c), Bilateria (p)

Perception: Decent vision with no depth perception either side, can sense chemicals up to ten metres away with accuracy.

Latest Mutations: Muscular Foot

Info: Previously, members of this heavily-shelled family lay sessile wherever the currents had taken them as youngsters and they had no way of moving after this. Now, a muscular foot attached to the end of the body exits the back of the shell and helps move Ostrapodia slowly along if it needs to find a new location. They live only in the Northern Hemisphere.

Intelligence / Behaviour: Processes information and responds based on fixed behaviours. It knows to eat and avoid being harmed. The female responds to the stimuli of producing eggs by embedding them in her tentacles and tucking the tentacles under her body.

External Features: Cylindrical body completely covered on back by dorsal and ventral valves of thick calcite shell with red pigmentation. It has a thin skin layer. At the head is a mouth with chemoreceptors and two tentacles. A muscular foot is attached towards the rear end.

Internal Features: Each cell contains lysozymes in addition to enzymes. There are three gill slits each side of the head. Muscles line 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 the head connects to one nerve cord which branches into a network of nerves, with a notochord running alongside. It hosts both 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.
