Kapnosta

## Kapnosta limus

Timespan: Tyrannidean to Gnathian Stages of the Atroxian (R.26 - R.52)

Habitat: Deep Ocean, Continental Slope (Mid Ocean)

Distribution: Under Temperate and Tropical Uteenessa Ocean

Niche: Benthic Filter-Feeder

Size: 6.5cm

Predecessor: Nassiaskulus oculimagnus

Classification: Kardiaskulidae, Kardiaskulidea, Tubulosa

Info: With a protective layer of heat-proof scales, this animal was able to get quite close to colder variants of hydrothermal vents, and live off the microbes that flourished in the rich water. They lived here in the highest densities, but also lived across the deep ocean. It's name means slimy smoker, a reference to this lifestyle. It was very common in its time, as they had an unchallenged source of food.

Description: It had a tubular, pigmentless cylindrical body with two large pinhole eyes with lenses on top of the head, and one facing forwards. On each side of the body was four gills, as well as a gill frill. A protective layer of slimy, heat-proof scales covers the body, and gives off a strong smell. A simple gut, behind the pharynx, led through the body, which was circulated by a semi-open circulatory system; capillaries covered the muscles, which also had special vacuoles, but the rest of the organs were bathed in a chamber. The circulatory system was pumped by a tubular heart. A tiny brain and two nerve cords controlled the body. The body has vertebrae made of cartilage.

## Kapnosta cuniculum

Timespan: Gnathian Stage of the Atroxian (R.43 - R.57)

Habitat: Shallow Sea

Distribution: All Temperate Seas

Niche: Benthic Filter-Feeder

Size: 6.5cm

Predecessor: Kapnosta limus

Classification: Kardiaskulidae, Kardiaskulidea, Tubulosa

Info: Although not very well known, this species was one of the first to recolonise the temperate shallow seas after they were ravaged by the emerging Thanostoma. They hid in the ground and stuck their heads out the filter-feed, much like garden eels on Earth.

Description: It had a tubular, green, cylindrical body with two large pinhole eyes with lenses on top of the head, and one facing forwards. Small tentacles grew from around the mouth. On each side of the body was four gills, as well as a gill frill. A protective layer of heat-proof scales covers the body. A simple gut, behind the pharynx, led through the body, which was circulated by a semi-open circulatory system; capillaries covered the muscles, which also had special vacuoles, but the rest of the organs were bathed in a chamber. The circulatory system was pumped by a tubular heart. A tiny brain and two nerve cords controlled the body. The body has vertebrae made of cartilage.

## Kapnosta eremitus

Status: CR

Timespan: R.43 - Present

Habitat: Hydrothermal Vents (Deep Ocean)

Distribution: Under Temperate and Tropical Uteenessa Ocean

Niche: Benthic Filter-Feeder

Nutritional Value: 50

Size: 8.5cm

Predecessor: Kapnosta limus

Classification: Kardiaskulidae, Kardiaskulidea, Tubulosa

Latest Mutations: Calcium Carbonate Shell, Heat Resistance, Tentacles

Description: Stuck to the chimneys of hydrothermal vents and the surrounding areas are hardy Kapnosta. They hide inside a limestone shell that they build around themselves which sticks to a surface permanently. They have evolved increased resistance to heat to survive such constant exposure to high temperatures. The only problem is that whilst they are safe inside their shells, they have tentacles used for catching particles of food hanging out, exposed.

Previous Mutations: Extra-Efficient Muscles, Open Circulatory System, Tubular Heart, Web of Capillaries Over Muscles, Axochord, Notochord, 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
