A semi-translucent pygmygoby with an irregular, internal reddish midlateral stripe, a white stripe along spinal column interrupted by reddish bars that extend ventrally, a row of small reddish spots along the dorsal midline, and narrow reddish bars usually above the anal fin. The first four dorsal-fin spines of males are often prolonged and filamentous, as are the first three dorsal-fin spines of females.

More Info


Scott Reef, Western Australia, Ashmore Reef, Timor Sea, to the northern Great Barrier Reef, Queensland. Elsewhere the species occurs in the Indo-west-central Pacific, from the Seychelles to Indonesia, north to Japan (Ogasawara Islands), east to Micronesia and Melanesia to Wallis and Futuna (a similar species occurs in Fiji and Tonga).


The maximum longevity of this species is 59 days, with a pelagic larval duration of three weeks and maturity within two weeks of settling on a reef. Adults reach sexual maturity at 1 to 2 centimetres and reproduce over a period of three weeks before death. The lifespan of this species is the shortest recorded lifespan of any vertebrate (Depczynski & Bellwood 2005). 
Depczynski & Bellwood (2006) showed that this species exhibits rapid linear growth, produces several broods of offspring during its short lifetime, and experiences exceptionally high daily mortality.
