Family:  Gobiidae (Gobies), subfamily: Gobiinae
Max. size:  3 cm SL (male/unsexed); max. reported age: 0 years
Environment:  reef-associated; marine; depth range 3 - 20 m
Distribution:  Indo-West Pacific: Seychelles to Indonesia, north to Japan (Ogasawara Islands); east to Micronesia and Melanesia to Wallis and Futuna; south to Australia (Western Australia and Great Barrier Reef). The species in the Philippines, Fiji and Tonga is considered E. cf. sigillata.
Diagnosis:  Dorsal spines (total): 7-7; Dorsal soft rays (total): 8-10; Anal spines: 1-1; Anal soft rays: 7-8. Characterized by semi-translucent body with irregular, internal reddish midlateral stripe; white stripe along spinal column interrupted by reddish bars that extend ventrally; row of small reddish spots along dorsal midline; usually with narrow reddish bars above anal fin; often prolonged and filamentous first four dorsal spines of male and first three of female; unbranched pectoral rays; longitudinal scale series 21-24; ctenoid scales, absent on head , nape and pectoral fin base; depth of body 4.3-5.0 in SL (Ref. 90102).
Biology:  Adults live for 59 days at the most, with larvae spending three weeks in the open ocean and maturing within two weeks of settling on a reef, leaving the adults (which are 1 to 2 centimeters long) just three weeks to reproduce. This strategy of 'live fast, die young' is perceived to be a response to intense predation. Daily mortality rate, from tag-recapture data, might be as high as 8% (Ref. 54199). Occur at depths less than 4 to between 17 and 21 m on sandy bottoms of lagoon reefs (Ref. 1602, 37816, 48637). Minimum depth from Ref. 58018. Spawning appears to be repeated on a regular cycle, semilunar or every 14 days (Ref. 116739).
IUCN Red List Status: Least Concern (LC); Date assessed: 09 March 2015 Ref. (130435)
