Distribution: Tartarus Brackish and Freshwater

Niche: Predator

Lifespan: 1 - 2 years

Size: 8cm (length)

Nutritional Worth: (9.6 x 8 =) 77NP

Predecessor: Ocuteras segmipano

Classification: Mandibulidontinae (sf), Ocuterasidae (f), Mandibulata (so), Critteroidea (sc), Bilateria (p)

Perception: Blurry vision with no depth perception on either side, blurry front vision with depth perception. Can perceive blue and green light.

Latest Mutations: Improve Bite Force = 6, Increase Size = 3, Legs = 4

Info: Large, tough pincers around the mouth can break through even the calcified exoskeleton of its cousin, Gempliaori and sharp barbs like teeth on the inside of the pincers shred up food into more manageable pieces. It hunts this other species but can also be found feeding on vegetation. Compared to Gempliaori it's four pairs of legs are rather simple, but they still help it walk around on surfaces and even briefly on land.

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

External Features: It has a cylindrical body with blue pigmentation, a proboscis and protected by a jointed, tough chitin shield. Slightly longer, touch chitinous pincers protrude from around the mouth, with sharp barbs. There are chemoreceptors on the proboscis. It also has two eyes on the front of the head and one compound eye on each side. Two receptor types means it has dichromatic colour vision. Spiracles sit behind the head. It has four pair of simple, chitinous legs. There is a chitinous fan-tail, above a hyponome, at the rear.

Internal Features: Each cell contains lysozymes in addition to enzymes. A network of vascular blood vessels circulates blue blood containing hemocyanin and anti-freeze proteins - the spiracles link to the major blood vessels. Also, a network of protonephridia expels waste through pores. Muscles on each side of the body are attached to the body wall. The gastrointestinal tract from the mouth has a muscular stomach with digestive juices followed by coiled intestines leading to the anus. A brain encased in the head connects to two nerve cords which branch into a network of nerves. There is a swim bladder in the middle, not connected to the gut. It hosts both male and female gonads. The body contains a coelom cavity, filled with a bitter fluid.

Latest Mutations: 3 = Lungs, 5 = Bigger, 1 = Less Armour

The way in which the chitin exoskeleton is formed is slightly different in this Mandibulidon because it is made heavier but not harder than other Mandibulidonts. It is slower and this is a significant disadvantage because its competitors hunt more quickly.

On its appearance, this arthropod breaks the record for arthropod sizes, which is necessary to prey on the 13cm long Salcaedis, which is a recent arrival on Aeaea. It's prey is a more accomplished swimmer but this predator doesn't use swimming to catch its prey. Instead, it lays camouflaged against mats of algae waiting for Salcaedis to come and graze on the algae, when the Mandibulidon then pounces.

Intelligence / Behaviour: Processes information and responds based on fixed behaviours. When feeling pain; roll up into a ball. When hungry; look or sense for algae or animals. In Early Spring, when ready to reproduce, move to brackish water and gather in specific breeding sites (+1 Evolution) and then sense for pheromones of opposite sex and move towards them, then attempt to mate with the source.

External Features: An unsegmented chitin carapace covers the top and sides of the cylindrical body. The structure creates a green sheen. Underneath, the skin is exposed. A pair of long, serrated mandibles lay on either side of the mouth. There are also chemoreceptors on the front and at the side of the head are a pair of lens eyes, then a pair of compound eyes both. From the side of the carapace are four pairs of jointed legs. At the end is a fan tail, extended from the exoskeleton, with a hyponome below.

Internal Features: The hyponome does not form much of a chamber. Spiracles dotted along the body contain gills. The mouth leads to a tube that reaches the stomach, which connects to the coiled intestines and this to the anus. A brain in the head connects to a nerve cord, which is connected to nerves that spread across the body like rungs of a ladder. Blood vessels cross all over the body. The blood is blue because it contains hemocyanin; it also contains anti-freeze glycoproteins. A muscular system exists in the body. There is a nephridium, a swim bladder and a sexual organ. A bitter fluid is produced by a sac. In the mandibles is a toxin gland.

## Mandibulidon viridus

Latest Mutations: Green

This is a small arthropod that feeds on algae along the rivers and lakes of Aeaea. It is coloured green, unlike it's predecessors.

Status: Unlisted

Habitat: Freshwater & Brackish Water in Subtropical Winter Semi-Arid Barrens, Subtropical Arid Barrens

Niche: Herbivore

Diet: Algae

Size: 8cm (length - head to end)

Nutritional Need: 187 x 8/100 = 7.4NP.

Food / Oxygen Requirement: 7.4 x 0.25 = 1.9NP per round (Needs to intake 1.9/0.7 = 2.4NP per round)/ 7.4NP.

Abilities: Anti-Freeze. Exothermic. Foul Taste. Large-Body Circulation. Liquid Excretion. Low Pressure Tolerance. Moults. Osmoregulation (Brackish and Freshwater). Roll Up. Solid Excretion.

Perception: Sight 2 (sees clearly up to 5m away at the front and sides, blue and green perception, side monocular vision, front binocular vision). Chemoreception 2 (chemicals 5m from mouth). Wide Vision 1 (wide field of view from sides that catches peripheral movement, monocular vision). Smell 1 (odours 1m from spiracles).

Stats: Buoyancy 1 (Adjustable Buoyancy). Coordination 2. Desiccation Resistance 1. Dexterity 1. Digestion 2 (100% Meat, Digests 70%). Evolution 1. Filtration 1. Immunity 1. Jumping 1. Pierce Strength 3. Reach 2. Respiration 1 (Ram Ventilation). Sharpness 1. Stamina 2. Strength 1. Support 2. Swim Speed 1.7. Toughness 2. UV Resistance 2. Walk Speed 1.5.

Intelligence / Behaviour: 1. Hungry > Search for food. 2. Food > Graze with mandibles and chela. 3.  Tired > Rest. 4. Pain > Swim Away. 5. Maturity > Reproduce.

External Features: A highly jointed, calcified exoskeleton with nine segments covers the skin, which contains green carotenoid pigments. Around the mouth on the proboscis is a pair of long, serrated, horizontal mandibles and a circle of chemoreceptors. It has two eyes (camera eyes with calcite lenses that change shape and that have no blind spot) on either side of the head. Behind these on each side is a (typical apposition) compound eye. Blue and green come cells can be found in all these eyes. Two chelipeds with long, serrated claws are held at the front of the body and there are four pairs of legs. The rear of the body has an exoskeleton fantail and below that a hyponome.

Internal Features: Each cell in the body contains a relatively small number of piezolytes. Spiracles lead into water-filled tubes. Glands near the skin secrete a foul fluid. Blood vessels run all throughout the body and in these vessels is an antifreeze (xylomannan fatty acid and polysaccharide). A system of muscles stretches across the body. Near the lower wall can be found the gonads as well as the large protonephridium and near the upper wall is the enclosed swim bladder. Through the mostly lower half runs the monogastric digestive system, from the mouth through the tubes to the stomach and intestines. Ganglia in the head connect to a dual nerve cord along the dorsal half, which has many nerves branching off it to encompass the whole body.

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

Castes/Phases: Almost identical male and females.

Locomotion: Active (20NP). Paddles with legs and fan tail, boosts with hyponome.
