They look like shell-less lobsters, pale and slimy on the surface with no identifiable head. When they hatch, they measure six inches and smell like rotting fish.

They have a natural mechanism that will emit a strong spark from one end of their body and the blast is usually strong enough to move them several inches, but their sparks occasionally cause surfaces to burn that are in a close distance to the beast.

The males sport a stinger at the other end and the females, although missing the stinger, have a sucker for blood on the underside. Skrewts have not been known to hibernate.
