Cryptasterina pentagona

''Cryptasterina pentagona'' is a species of starfish in the family Asterinidae. It is found in shallow waters in north eastern Australia. Its life cycle includes the release of large-yolked eggs and the development of planktonic larvae which is in contrast to the very similar ''Cryptasterina hystera'' which is viviparous. The two appear to have diverged from a common ancestral line only a few thousand years ago.
==Description==
As its name suggests, ''Cryptasterina pentagona'' is pentagonal, with five short rays with rounded tips. The body is covered by an integument and the plates (''ossicles'') are arranged in a longitudinal series along the rays. There are papulae in a row along the edge of the rays and scattered over the aboral (upper) surface, which is covered by spiky granulations. There are no pedicellariae. The oral (lower) surface is flat while the aboral surface forms a low dome.
