This species came from a very successful lineage that dominated the Atrobocean stage of the Oliverian as apex predators and continues to to this day. They are lobe-limbed arthropods with two fan tails, making them proficient swimmers, as well as having a spring-loaded cheliped. The same success cannot be said to be had for this experimental filter-feeder. The mouth became even smaller so as to become little more than a pore - a unique net-like appendage extended from the mouth to filter food. Though the appendage itself was quite efficient, the repositioning of the mouth on the underside was not ideal and the mandibles often got in the way, ripping the net. This species simply could not survive long because it's filter-feeding abilities are not enough to feed an animal of it's size. They have also evolved lysozymes to protect them from the cold but it is not enough to save them. It did not seem to last long before going extinct.

External Features: It has a cylindrical body which has a calcified, calcite exoskeleton in fourteen plates with joint tissue in between. The skin underneath has sandy melanin pigmentation on top and white melanin pigmentation underneath. One pair of legs have chela on the end. The pore-like mouth is on the underside of the head, fronted by a pair of mandibles. A soft, flexible net that has the structure of a tree with many branches, getting smaller each offshoot, extends from the mouth also and can be curled up. Around the mouth are a few chemoreceptors. On either side of the head is a camera eye with calcite lens that changes shape and has no blind spot and a typical apposition compound eye, which both contain blue and green cone cells. Not including the chelipeds, it has four pairs of normal legs, one to a segment, that have a large paddle on the outer side. When swimming, these are folded in to give the effect of a continuous lobe halfway along the body. Behind that is five pairs of biramous, paddle-lined swimmerets, one to a segment. The rear of the body has two fan tail lobes and below that a hyponome. Males in the mating season have a series of blue stripes on their limbs, unique to the species.

Internal Features: The body is segmented and contains fourteen segments. Each cell has piezolytes and lysozymes. Spiracles lead to aquatic trachae. Blood vessels travel past every cell, carrying blue blood caused by hemocyanin, and the double circuit has a three-chambered heart. An anti-freeze xylomannan fatty acid and polysaccharide is in the blood. The body is supported by a system of muscles. It has a sex-appropriate gonad and a large protonephridium. There is a enclosed, one-chambered swim bladder in the dorsal side. There is a stomach and coiled intestines. A gland releases a foul fluid into the body fluids. Ganglia in the head lead into a dual dorsal nerve cord that has many nerves branching off. A cerebrum has memory neurons.

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

Castes/Phases: Almost identical male and females. (Changes - Male = Adulthood > Blue Stripes on Legs).

Locomotion: Active (20NP). Usually moves by undulating fan tail and legs folded into lobes and propels itself with the hyponome. Can walk over surfaces.
