Diplopygus

## Diplopygus ramstirpes

Latest Mutations: Three-Chambered Heart = 5, Speed = 6, Bigger = 5, Brain = 6

An arthropod species with legs that become lobes for swimming and dangerous chelipeds. It is a predator and hunts some of the bigger animals around. It lives in tropical seas, oceans and estuaries as the apex predator and the largest arthropod to exist so far. Diplopygus differs from its predecessors, on top of being much bigger, by having a three-chambered heart pumping a double circulatory system. It also has a faster hyponome and ends in a pair of fan tail lobes. Furthermore, it has a slightly better brain and buries its eggs with food. Cannibalism is also relatively rare.

Intelligence / Behaviour: Stimulus Response. Subconscious Functions. Body Movement Control. Tiredness = rest. Hunger hormones = move around. Pain = roll up. Adult = Release mating hormones. Mating hormones = move to Tropical Shallows breeding sites. (FEMALE ONLY: Mating hormones + own species chemicals + perceive blue stripes = reproduce). (MALE ONLY: Mating hormones + own species chemicals + perceive no blue stripes = reproduce). Move signal in water = fold legs against body to create lobes, hyponome boost and paddle with fan tail. Move signal against a surface = walk. ??? = move towards, wind up cheliped then launch it. 1) Digs a hole for eggs and then buries them. 2) Deposits food in hole for eggs. 3) Do not cannibalise unless starving.

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. In front of the circular mouth is a mandible. 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. 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.
