Threadfin Reefgoby
Priolepis nuchifasciata
A diminutive and cryptic goby species occurring on reefs of subtropical and tropical Australian waters. The colour pattern features reddish-orange scale margins on the body and a series of dark-edged pale stripes on the orange-yellowish head and forebody. Fins are transparent featuring rows of reddish-orange spots.
Morphology
Elongated, tubular body with two separate dorsal fins and a bulbous, rounded head. The first dorsal fin is extended into a long filament. Distinguished from other Priolepis by having a pelvic fraenum (i.e. flap of skin connecting the pelvic fin bases) and branching dorsal fin rays. The maximum size is 4 cm.
Evolution
Belongs to a fairly diverse genus containing 34 species. Very closely related, and virtually indistinguishable to the naked eye from Priolepis semidoliata.
Behaviour
A small, bottom-dwelling, cryptic species, usually sheltering in caves and crevices on reefs.
Method of reproduction
Sexual. No details are known of the reproductive biology.
Habitat
Marine/Estuarine
Inhabits rocky, rubbly and coral-covered reefs from 5-30 m depth.
Distribution
Indo-West Pacific, from sub-tropical latitudes of the western and eastern coasts of Australia north to Hong Kong.
