Neoxirnikrozz

## Neoxirnikrozz cormeus

Temporal Range: R.126 - R.139 (Untrustolithic to Gammavian Stage of the Atroxian)

Habitat: Temperate Shallows

Distribution: Southern Hemisphere

Niche: Apex Predator

Size: 46cm (length)

Nutritional Worth:

Predecessor: Xirnikrozz crusherei

Classification: Peragapodusinae (sf), Thanostomidae (f), Flagracauda (so), Caudomorphii (c)

Perception: Blurry vision with no depth perception on either side, can see well in low light, can use electroreception up to ten metres away, can accurately smell odours up to tens of metres away

Latest Mutations: Heart, Larger

Info: The record for largest animal on Ezta had once again been broken, this time by Neoxirnikrozz, almost half a meter in length. This comparatively large predator dominated the temperate shallows around Tartarus, feeding on the large herbivores. It was forced to evolve a primitive heart to pump blood around this large body.
The dominance of its kind could only be stopped by the Gammavian Extinction.

Anatomy: This species has a long, blue body that tapers into a whip-like tail, armed with two toxic spikes. It's muscular jaw is made of cartilage but reinforced with a layer of tessarae and it has serrated teeth here. On each side of the head is a pinhole eye and olfactory receptors are also found on the head. Behind the retina is a layer of cells containing reflective crystals called a choroidal tapetum cellulosum. Along the side of the body, are three gill slits near the front, and line of electroreceptors. There are four paddle-like limbs of flesh, cartilage and muscle. Inside, they have a gut with a stomach containing carnivorous digestive enzymes, and connected to the gut is a swim bladder. The open circulatory system contains red blood is pumped around by a smal one-chambered heart in the ventral area. It's brain also contains an olfactory lobe. The muscles are strong and energy-efficient. Finally, supporting the entire body is a spine of cartilage vertebrae.

Behaviour: This species is capable of processing information gathered from sense receptors and using that to form a picture of its surroundings. It can then respond to stimuli. It also has basic reasoning. Other than its standard survival responses, Xirnikrozz always try to be vigilant of their surrounding, they avoid eating their own kind and they also remain close to their eggs until hatching.

Latest Mutations: Genders, True Eyes, More Rods

Info: True eyes with a retina coming both a tapetum and many rod cells, can pick up very faint light, making it possible for it to have hunted at night. They also had male and female castes, which increased the rate of evolution. Their brief reign was cut short by the Gammavian Extinction.

It's muscular jaw is made of cartilage but reinforced with a layer of tessarae and it has serrated teeth here. On each side of the head is an eye and olfactory receptors are also found on the head.
