Environment / Climate / Range
Marine; reef-associated; depth range 0 - 17 m (Ref. 37816). Tropical
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 1 - 2 cm
Max length : 3.0 cm SL male/unsexed; (Ref. 48637); max. reported age: 0 years (Ref. 58013)
soft rays: 7 - 8. Differs from E. storthynx by lacking a post ocular spot, and from E. zebrina by having dark spots on the upper and lower portions of the caudal base instead of a central dark spot.
Indo-West Pacific: Seychelles to the Great Barrier Reef and Micronesia, north to the Ogasawara Islands (Ref. 26066). Recently reported from Tonga (Ref. 53797).
The species lives 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). Occurs 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.
