Toothed Ponyfish, Gazza minuta (Bloch 1797)

More Info


Distribution

Exmouth Gulf, Western Australia, to Currimundi Lake, southern Queensland. Elsewhere the species occurs in the tropical, Indo-west-central Pacific: East Africa to Tonga, north to Japan, south to New Caledonia. Schools inhabit estuaries, near river mouths and coastal waters over sandy/mud and muddy areas. Juveniles enter estuaries.

Features

Dorsal fin VIII,15-17; Anal fin III,13-14.
Mouth protruding forward; canine teeth in both jaws; Body oval, somewhat compressed, depth 2.2–3.5 in SL; dorsal and ventral profiles equally convex; mouth pointing forward when protracted; head and breast naked; distinct canine teeth in both jaws; anterodorsal scaled area on nape reaching to tip of posterior branch of supratemporal sensory canal. 

Feeding

Feeds on small fishes, crustaceans, and polychaetes.

Biology

Ponyfishes are bioluminescent, and harbour colonies of the biolumnescent bacterium, Photobacterium leiognathi, in a circumesophageal light organ. This luminescent system is sexually dimorphic, enabling males to use species-specific patterns of lateral bioluminescent signaling to attract mates in turbid coastal environments (Sparks et al, 2005)

Etymology

The specific name is from the Latin minutus (= small), presumably in reference to the small size of this species.
