Etymology: Eviota: No etymology given, suggested by Christopher Scharpt: from Latin 'eu' for 'true' and 'iota' for anything very small, in combination 'truly very small' referring to it as being the smallest vertebrate at the time it has benn described by Jenkins (thus, making the suggestion by Scharpt plausible.; pellucida: Name from Latin 'atrus' for black and 'venter' for belly, referring to the black pigment in the area of the abdomen; an adjective. More on author: Larson.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 3 - 30 m (Ref. 46956). Tropical; 22°C - 25°C (Ref. 27115); 14°N - 18°S
Western Pacific: Japan (Ryukyu Islands), Micronesia (Pohnpei, Guam, Marshall Islands, and Kiribati (Abaiang Atoll). Other country records represent Eviota atriventris.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.1 cm SL male/unsexed; (Ref. 46956)
soft rays: 7. This species belongs to the cephalic sensory-pore group 2 with the following characters: lacking only the IT pore, has simple pectoral-fin rays, a dorsal/anal fin-ray formula almost always 8/7, and with the 5th pelvic-fin ray longer than 30% of the length of the 4th ray; however, its abdomen is not black. It is most easily confused with E. prasites and E. spilota (Ref. 89418).
Collected from 3m to at least 12 m depth (Ref. 1602). Reported to be associated with the mushroom Heliofungia actiniformis (Ref. 91291).
