Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0. Mouth well in front of eyes; spineless dorsal fins far posterior on tail; greatly elongated thick precaudal tail, long and low anal fin just anterior to caudal fin, prominent predorsal and interdorsal ridges on back, dorsal fins with nearly straight posterior margins, first dorsal-fin origin opposite or just behind pelvic fin insertions, second dorsal fin usually with a longer base than first; no color pattern (Ref. 43278).
Body shape (shape guide): elongated.
Inhabits coral reefs, rocky shores, and mangrove estuaries. Free-living at 10.1 cm TL. Feeds on squid, shelled molluscs, crustaceans, and snake eels (Ref. 43278). Oviparous (Ref. 50449). Of minimal interest to fisheries (Ref. 43278). Caught rarely by demersal trammel and trawl fisheries operating inshore. Utilized for its meat and possibly fins, but of limited value due to its small size (Ref.58048).
Livscykel och parningsbeteende
Könsmognad | Reproduktion | Lek | Ägg | Fekunditet | Larver
Oviparous. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205). Lays up to four egg-cases on coral reefs which hatch after 70-80 days (Ref. 43278).
