1. A biological term meaning the shedding of an outer hard layer(like cuticle), such as done by a snake or a crustacean when it's molting.

2. A strip performance, as done by an ecdysiast.
Snakes are known to perform an ecdysis in order to grow a new outer layer. Interesting, but I'm more interested in the other form of ecdysis performed by females of the human species.

This snake lives in an unusually hot box (cage), and as a result, visitors to the Shed Zoo often see it in its ecdysis state.
