Summary:
A transparent compressed goby with small scattered black spots on the underside of the head, a line of melanophores along the side, a series of small black spots along lower margin of the body from the origin of the anal fin to the caudal-fin base, and tiny pelvic fins.
Glassgobies inhabit coastal bays, inlets and estuaries, often forming large schools close to shore.

Glassgoby, Gobiopterus semivestitus (Munro 1949)

More Info


Distribution

Endemic to eastern and southern Australia from about Townsville, central Queensland, to Spencer Gulf, South Australia, excluding Tasmania. Occurs in shallow estuaries, coastal bays and inlets, and often enters freshwater.
Although the Glassgoby is abundant in New South Wales, where it forms large schools, the species is rarely noticed due to its small size.

Features

Dorsal fin V + 7-10 (usually 9); Anal fin 11-13; Caudal fin (segmented rays) 17; Pectoral fin 14-15; Pelvic fin i, 5.
Body slender; head of moderate size (28-31% SL); interorbital broad, slightly less than eye diameter; mouth very oblique, almost vertical, front of jaws in line with upper quarter of eyes, rear end of jaws below or just before anterior margin of eyes; teeth in males large and flattened (anteriorly-posteriorly); teeth in females minute and conical; head pores absent; gill openings broad, extending forward to below posterior preopercular margins; tongue tip bilobed. 
Head naked; body scales ctenoid, in 16-18 vertical rows, confined to posterior half of body, beginning just before second dorsal fin origin; no scales immediately behind pectoral fin bases. 
Two dorsal fins, first dorsal fin minute, origin well behind pelvic-fin insertions; second dorsal and anal fins very short based, base much shorter than caudal peduncle length; second dorsal-fin origin well behind first dorsal fin; anal-fin origin below second dorsal-fin origin; caudal fin with truncate to slightly emarginate margin. Pectoral fins of moderate size, reaching about to anal-fin origin. Pelvic fins minute, bar-like and fused, origin below and just behind pectoral-fin insertions.

Size

Reaches a length of 3.5 cm.

Etymology

The specific name semivestitus is from the Latin semi- (= partial) and vestitus (= clothed), possibly in reference to the fact that the body scales are confined to the posterior half of the body.
