(rudimentary). Lower l -4 of 1st gill arch bound to gill cover by membrane.
Gill opening restricted to P base. Pre dorsal naked.
Found on Acropora. Attains 2.2 cm. Sodwana Bay,
Seychelles, Chagos Archipelago, tropical Indian Ocean and
western tropical Pacific.
Genus Prio/epis Ehrenberg, 1837
Gill opening extending to below rear preopercular margin; head broad; outer teeth of upper jaw widely spaced;
lower jaw truncate when viewed from below; V united; V
frenum rarely present; head pores absent; sensory papillae
reduced to a transverse pattern; scales ctenoid, large. Second D 1,9-11; A 1,7-9; P 16-21; LS 23-32. Vertebrae 26. Easily confused with Trimma, which has a broader gill opening
and the extralimital Lubricogobius, which has few or no
scales. A tropical and subtropical genus found on coral or
rocky reefs. About 15 species, 3 in our area.
