Kappa Reefgoby, Priolepis kappa Winterbottom & Burridge 1993

More Info


Northern Great Barrier Reef, and reefs in the Coral Sea, to One Tree Island, Queensland. Elsewhere the species occurs in the Indo-west Pacific (east to Fiji).
Inhabits reef crevices on shallow reef tops with sandy or silty bottoms, back reef slopes, tidal reef flats, mixed rubble, and patch reefs.


Species of the genus Priolepis form monogamous pairs, and are capable of bidirectional sex change. In laboratory experiments with female-female pairs, the larger individual changed sex to male, and in male-male pairs, the smaller changed to female. The gonads of these species simultaneously formed ovarian and testicular portions with an accessory gonadal structure (Manabe et al. 2013).
