Trachodermus

## Trachodermus ooferei

Latest Mutations: 6 = Sexes, 5 = Tough skin, 2 = Improve digestive system to absorb more nutrients

Distinctive by the lumps of keratin that cover the skin, Trachodermus is a Sanicthyopsine that lives only in the tropics. It competes with Anazitonta anazitonta for prey, which is slightly faster but Trachodermus has a defensive advantage. However, Trachodermus has a shorter and less effective intestine. They have different reproductive methods because Trachodermus has sexes, which can also be swapped when there is too few of a certain sex around.

Abilities: Bioluminescence. Short-Term Memory.

Perception: Blurry sight. Can detect electrical signals up to tens of metres away and smells up to ten meters away.

Intelligence / Behaviour: Processes information and responds based on fixed behaviours. It knows to eat and avoid being harmed.

External Features: Streamlined fish-shape body with black pigmentation; it has oval pectoral ray-fins, a caudal fin beneath the tail and two spines on it's base. Cycloid scales cover the keratinised skin layer containing keratin scutes, a line of electroreceptors on the flank and blue autogenic photophores dot the body. A mouth containing lots of razor-shaped teeth, olfactory receptors and upwards facing pinhole eyes make up the face.

Internal Features: Migmachordatix toxin is produced and secreted into spines. Three gill slits sit each side of head. A network of vascular blood vessels circulates red blood containing hemoglobin. Muscles line either side of the body between the body wall and the cartilage membrane. The mouth is supported by a cartilage jaw. The gastrointestinal tract from the mouth has stomach a with digestive juices followed by short intestines leading to the anus. A slightly bigger brain, with a memory lobe, encased in the head connects to two nerve cords which branch into network of nerves. A swim bladder lies in the centre of the body, near to the electric organ. It hosts male and female gonads. Protonephridia, connected to hemacoel, expels waste through pores.

## Trachodermus pharyngus

Latest Mutations: Muscular Pharynx

As this proto-fish is slower than some of its contemporaries, it's biology has adapted; instead of going to prey, it has a muscular pharynx to bring the prey to it - by suction. Even though it still has to swim up to its prey it now just has to be close and the force of negative pressure draws prey into the mouth.

Status: Unlisted

Habitat: Tropical Shallows, Tropical Upper Ocean

Niche: Predator

Size: 5cm (length)

Nutritional Need: (183NP/10) x 5/10 = 9.2NP

Food / Oxygen Requirement: (9.2 x 0.6) x 0.95 = 5.2NP / 9.2NP

Abilities: Air Space. Barrier Immune System. Bioluminescence. Circulation. Fatal Toxin. Gas Buoyancy. Liquid Excretion. Penetrates Hardness 1 (jaw). Ram Ventilation. Short-Term Memory. Solid Excretion. Strong UV Resistance. Suction.

Perception: Blurry Sight (Upwards field). Electroreception 1 (1 body length away, sideways field). Smell 1 (Detects smells).

Stats: Agility 1. Buoyancy 1. Coordination 1. Digestion 1.5 (Can break down multicellular matter, can digest meat, 5% off). Desiccation Resistance 1. Filtration 1. Hardness 0.5. Intelligence 1.

Intelligence / Behaviour: Processes information and responds based on fixed behaviours. When observing a predator; swim away. When hungry; look for prey. When ready to reproduce, smell for other adults and move towards them, then attempt to mate with the source.

External Features: The fish-shaped body has black melanin pigmentation in its keratinised skin. The mouth contains razor sharp teeth and has a pair of olfactory receptors above it. There are also upwards facing pinhole eyes on top of the head. A line of electroreceptors flanks the body. It has oval pectoral ray-fins and a semi-circular diphycercal caudal fin beneath the tail. At the base of the tail is a pair of spines. The whole of the body is covered in cycloid scales, keratin scutes and blue autogenic photophores.

Internal Features: Migmachordatix toxin is produced and secreted into spines. Three gill slits line just behind the head. A network of vascular blood vessels circulates red blood containing hemoglobin. There is also a nephridium and the body is lined with muscle. The mouth is supported by a cartilage jaw. Food enters the stomach and then the short intestine before exiting the anus. A brain, including memory lobe, leads to a nerve cord with nerves running off like rungs on a ladder. The nerve cord is supported by a cartilage vertebrae. In the centre of the body is a swim bladder and below this are the testes in males and ova in females, with both in hermaphrodites.
