Poison Urchin

==Appearance==
The Poison Urchin has a spherical body with a purple test, two sets of thick, dark blue spines in joints, one longer and the other shorter alternately, and short pedicellariae with three red valves in between those. The spine tips are a bit apart when straight being so thick but they are still numerous, altogether longer at the equator and shorter on the poles. The mouth is beneath, the arrow-shaped red pyramids surround the orifice and the lantern inside is white. Poison Urchin have blue plates on the periproct and tube feet all over its body that grow from pores in the test with which it moves around.
==Habitat and Ecology==
The Poison Urchin's habitat are the coral reefs in the Frantic Bay and the Submerged Boneyard often found in between some corals and rocks or on the ground half-covered in sand. Reef Koyuxerus also often keeps the Mollusk within the reef it carries around. The Endemic Life is mainly herbivorous and feeds on algae on rocks and corals as well as algae and rarely small parasites from the body of the Carapaceon it lives on. In return the monster protects it from predators, though sometimes the Poison Urchin gets held in its claw or even thrown.
As the Mollusks are often found half-buried in the sand both monsters not acquainted or distracted as well as hunters step on or swim into it. The spines hold a potent venom which gets injected in such situations, most native monster know to avoid it though. Reef Koyuxerus knows to use this aspect and sometimes throws Poison Urchins to hit threats or at least put them in the way of them. Single spines or parts of its test with them are often used by experienced hunters as slinger ammo. There are still predators who are able to prey on it despite of the strong venom certain Bird Wyverns even steal the poison to use it for defense themselves. Its vibrant color pales drastically outside of the water to the disappointment of collectors that adore its beautiful coloration.
In regular intervals female Poison Urchins release eggs that attaches to its spines. The male releases gametes into the water fertilizing the eggs when getting into contact. Both bilateral larval stages take place on the spines which they are attached to with their right side, only the adult form gets ejected out of the mother's protection. The larvae feed on freeswimming plankton but also ingest the venom of their mother which makes its own venom more potent. A good amount of eggs don't have a chance to grab ahold on a spine but still develop to a larva in which case the development is similar to other sea urchins, though the potency of the venom is lower than the larvae that developed on their mother. As Reef Koyuxerus gathers both female and male individuals on its body or arranges them in the surrounding area, the succession rate of reproduction drastically increases nearby the Carapaceon.

==Notes==
*Preyed on by:
*Feeds on: mainly algae, rarely parasites on Reef Koyuxerus
*As the Mollusks cannot flee fast enough, they usually point their spines towards threats it perceives through water movement.
**When a Reef Koyuxerus is closeby when capturing several of these Endemic Life, it will get provoked
*Sometimes spines or parts of its test with spines can be found, these can be used as slinger smmo inflicting poison.
*Poison Urchins can often be found on the back of Reef Koyuxerus.
==Obtainable Rewards and Materials==
*Rewards for capture: 90 Research Points
*Materials left behind: Poison spine (slinger ammo, rare)
