Bythitidae (Livebearing brotulas)
Etymology: Microbrotula: Greek, mikros = small + Latin, brotula, -ae = little, bud, shoot (Ref. 45335); bentleyi: Named for Andrew Charles Bentley of Port Elizabeth, South Africa, now at the University of Kansas, USA, for his enthusiasm and help in the development of a program on western Indian Ocean fishes, and for collecting the holotype..
Environment: milieu / climate zone / depth range / distribution range
Ecologie
marien rifbewoner; diepte 0 - 55 m (Ref. 54832). Tropical
Indo-Pacific: South Africa to the Red Sea and from the Philippines to Cape York Peninsula in northern Australia; widely distributed and large gap in the distribution is probably a collecting artefact rather than indicative of a true distribution.

Korte beschrijving
Morfologie | Morfometrie
Dorsale zachte stralen (totaal): 61-70; Anale zachte stralen: 50 - 57; Wervels: 44 - 47. This species is distinguished by the following characters: vertebrae 11-12+33-35=44-47; fin rays, on dorsal 61-70, anal 50-57, pectoral 15-17, caudal 7-8; anterior dorsal fin ray above vertebra number 7-8, anterior anal fin ray below dorsal fin ray number 12-16, anterior anal fin ray below vertebra 13-16; small forward-curved spine at lower angle of preopercle, hidden by skin; fleshy interorbital width 4.5-7.0% SL; palatine teeth papillae-like or absent (Ref. 88975).
Found from near the surface to 55 meters in protected reef structures (Ref. 54832). Solitary inhabitant of reef crevices, cryptic (Ref 90102).
