Zestoskulus

## Zestoskulus guardius

Status: NT

Timespan: R.66 - Present

Habitat: Deep Ocean, Continental Slope (Mid Ocean)

Distribution: Under Temperate and Tropical Uteenessa Ocean

Niche: Benthic Filter-Feeder

Nutritional Value: 50

Size: 8.5cm

Predecessor: Zestoskulus eremitus

Classification: Zestoskulusidae, Kardiaskulusidea, Kardiarchia
Latest Mutations: Shell Flap, Adult Form

Info: The end of the calcium carbonate tube has a flap which can close when threatened by predation. As well as the juvenile form which finds a place of attachment, the adult form at complete maturity breaks free of its tube to go and search for a mate.

Description: It has a cylindrical calcium carbonate shell covering most of its body, with a sticky end and a flap on the front. Two large pinhole eyes with lenses are on top of the head, and one facing forwards. Small tentacles grow from around the mouth. On each side of the body is four gills, as well as a gill frill. A protective layer of heat-proof scales covers the body. A simple gut, behind the pharynx, leads through the body, which is circulated by a semi-open circulatory system; capillaries covering the muscles, which also have special vacuoles, but the rest of the organs are bathed in a chamber. The circulatory system is pumped by a tubular heart. A tiny brain and two nerve cords control the body. The body has vertebrae made of cartilage.

Previous Mutations: Extra-Efficient Muscles, Open Circulatory System, Tubular Heart, Web of Capillaries Over Muscles, Axochord (L), Notochord (L), Four Gill Slits, Two Gill Frills, Pharynx, Large Pinhole Eyes With Lenses (2 on top of head, one on front), Heat-Proof Scales, Cartilage Vertebrae, Calcium Carbonate Shell, Heat Resistance, Tentacles
