Hoolar Crab

Hoolar crabs are a large species of predatory crabs that feed on their own species. Hoolar crabs are obligate cannibals due to lacking the proteins to make their shells harden. They are considered crab beasts.
Hoolar crabs kill intruders to their feeding grounds via decapitation.
They can imitate voices, and cooperate with other hoolars telepathically. Work in mating pairs mostly. If too many Hoolar are present in an area, they slowly destroy the shorelines and sink islands, by undermining them with tunnels. They maintain impeccable crab colonies, which is their food source. The colonies are often overseen by a brooding pair, their children leave once they are born to find new colonies to oversee. 
Hoolar crabs display rare intelligence for carcinoforms, they maintain their colonies to such an extent that they will actively seek to correct whatever could jeopardize the colony. Hoolar crabs have been observed replanting algae and trees where they were lacking, removing disease blooms, providing food for their charges, bringing live species for them to feed on, to even growing crops for their colony and of course eliminating any predatory animals.
