Aberration Crabs

Large crabs filled with writhing tentacles, some of which can be seen between the joints of the creatures carapace. These creatures were first discovered on the shores west of the New Pyleaus colony and appeared to be residing in a small tide-cave.

Behavior
The crabs appeared to be aggressive and attacked on sight. Once injured girevously enough, they enter a death frenzy attacking anything nearby with claws and bites before expiring.

They also appear to have some sort of hording instinct, keeping refuse and debris in the small tide cave.

Biology
The crabs are able to infect opponents with a strong poison via their bite, causing their opponents to weaken.

A larger variety of the creatures were also found in the tide cave, though it is unknown if this is a natural progression of the creatures or a rare occurrence.

The creatures reproduce by laying eggs that must be kept in a watery environment.
