Chirodectes

Chirodectes is a very rare, monospecific genus of box jellyfish in the family Chirodropidae.

The first and only scientifically studied specimen was captured from the outer edge of the Great Barrier Reef – about off the coast of northeast Queensland – on 2 May 1997. It was found within of the surface, and the researchers who first described it speculated that it may have been relocated to the area by Cyclone Justin. Its bell measured approximately in height, and it could only be observed for several hours in an examination lab due to how delicate it was.
