Glistroskulus

## Glistroskulus louixi

Timespan: Gnathian to Fressian Stages of the Atroxian (R.44 - R.66)

Habitat: Deep Ocean, Continental Slope (Mid Ocean)

Distribution: Uteenessa Ocean

Niche: Benthic Filter-Feeder

Size: 2cm

Predecessor: Squickia visionii

Classification: Squickidae, Squickidea, Tubulosa

Info: This animal was a pioneer - the first to extend into polar water, where competition did not exist. It was very widespread and very common, spreading into almost all saltwater areas, bar tropical water. It survived for over 5 million years until it was replaced by a newly evolved ancestor.

Description: The yellow, tubular body had a fleshy membrane running along the top and underside. Chemoreceptors sat by the mouth with three gill slits at the back of the head. On top was a singular pinhole eye covered by a lens. At the front of its nervous system, was a tiny brain. Its mouth had a primitive gut leading straight to the anus. An open circulatory system bathed organs and muscles in hemacoel; this contained anti-freeze proteins to stop bodily fluids from freezing. The length of the body was supported by a notochord.

Cause of Extinction: Outcompeted

## Glistroskulus challengeri

Status: NT

Timespan: R.54 - Present

Habitat: Deep Ocean

Distribution: All Deep Ocean, Minimum Depth of 6000m

Niche: Benthic Filter-Feeder

Nutritional Value: 6.8

Size: 2cm (length)

Predecessor: Glistroskulus louixi

Classification: Squickidae, Squickidea, Membrania

Latest Mutations: Lose Notochord

Info: Below 6,000m, where only the least complex of animals can survive, are found jellyfish and now the benthic filter-feeder Glistroskulus challengeri. Without the calcium carbonate notochord, it can now survive the pressures of the depths which trenches sink to, and can be found at the very bottom, where nothing but jellyfish compete against it. Glistroskulus challengeri lives on the small amount of marine snow that sinks this far down.

Description: The yellow, tubular body has a fleshy membrane running along the top and underside. It has a single pinhole eye with a lens, facing forwards. Chemoreceptors sit by the mouth with three gill slits at the back of the head and it has tiny teeth in its round mouth. Its mouth has a primitive gut leading straight to the anus. At the front of its nervous system, is a tiny brain. An open circulatory system bathes organs and muscles in hemacoel; this contains anti-freeze proteins to stop bodily fluids from freezing. It's back is supported by an axochord.

## Glistroskulus sensei

Status: NT

Timespan: R.66 - Present

Habitat: Mid Ocean, Deep Ocean

Distribution: All Deep Ocean, Minimum depth of 500m

Niche: Benthic Filter-Feeder

Nutritional Value: 7.6

Size: 2cm (length)

Predecessor: Glistroskulus louixi

Classification: Squickidae, Squickidea, Membrania

Latest Mutations: Improved chemoreceptors

Info: This species have become the most common at the bottom of the ocean. It's chemoreceptors can detect the chemicals from potential food over tens of meters away. This makes them more successful.

## Glistroskulus octobranchium

Status: CR

Timespan: R.108 - Present

Habitat: Tropical, Temperate & Polar Deep Ocean

Distribution: Cosmopolitan

Niche: Benthic Filter-Feeder

Size: 2.3cm (length)

Predecessor: Glistroskulus sensei

Classification: Squickinae (sf), Squickidae (f), Tunicaphora (o), Cylindrea (c), Bilateria (p)
Latest Mutations: Immune System = 2, Carnivorous Digestion = 1, More Gills = 5

Info: At the bottom of the ocean, Glistroskulus were forced to evolve as chitinous Schedocavoura take over their territory. However, this particular evolutionary gamble has not paid off; they have eight gill slits instead of three, helping them breathe in less oxygenated water, but they also have digestive enzymes that do not break down food but gradually erode away at the animals insides until death and an immune system that simply shuts off the part of the body that has been affected. Their numbers are very small and have a fragile population.

Description: The yellow, tubular body has a fleshy membrane running along the top and underside. It has a single pinhole eye with a lens, facing forwards. Chemoreceptors sit by the mouth with eight gill slits at the back of the head and it has tiny teeth in its round mouth. Its mouth has a primitive gut leading straight to the anus, containing enzymes that erode at the gut lining. At the front of its nervous system, is a tiny brain. An open circulatory system bathes organs and muscles in hemacoel; this contains anti-freeze proteins to stop bodily fluids from freezing. It's back is supported by a notochord and muscles run the length of the body. It can shut off parts of its body when infected.
