Summary:
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
Distribution |
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). |
Biology |
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. |
