Turtle-shellers, sometimes known in the Rendi as murder hermits, are crab-like crustaceans that feed almost exclusively on turtles and tortoises. They may also feed on small lizards or fish, if the opportunity arises.
They feed on the soft tissue of their meal before, similar to their hermit crab cousins, slipping into the shell for protection against their own predators. This behaviour is what earned them their name.
Turtle-shellers are found all over Demrefor, in both fresh and salt waters. Though it is generally believed they originated along the coastlines of Yali there is no proof that this is true.
They are considered a delicacy among the Eala races, often used in expensive dishes, and an almost-inedible pest among aquatics.
