Istiblennius steindachneri

Istiblennius steindachneri is a species of combtooth blenny found in the western Indian Ocean. It can reach a maximum of 11 cm  in SL. The identity of the person honoured in this blenny's specific name was not stated by Pfeffer in his description but it is almost certainly the Austrian ichthyologist Franz Steindachner (1834-1919).
