Signal Goby, Cryptocentrus insignitus (Whitley 1956)

More Info


Distribution

Endemic to northern Australia from the Kimberley Region, Western Australia, to Gove Harbour, Northern Territory. Inhabits sandy and rubble areas on coastal reefs, sharing burrows with alpheid shrimps.

Etymology

"The ocellus on the spinous dorsal suggests one of the bats with which servicemen signal approaching aircraft to land on a carrier's deck, hence the generic name, Batman. Possibly the fish signals to others of its kind by erecting the dorsal fin to show the ocellus which would be hidden when the fin is laid back: insignitus is Latin for "marked so as to be known," from insigne, a signal. For this fish I suggest the vernacular name Signal Goby." Whitley, 1956.
