पृष्ठीय रीढ़ (सम्पूर्ण) : 1; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 69 - 115; गुदा कांटा: 0; ऐनल सौफट रेज़: 58 - 82. This species has the dorsal and anal fins continuous with caudal fin; with 4 pairs of mouth barbels; and a single highly venomous serrate spine at the beginning of the first dorsal and each of the pectoral fins (Ref. 1602).
Body shape (shape guide): fusiform / normal; Cross section: circular.
Coastal benthic (Ref. 68964). The only catfish found in coral reefs. Also found in estuaries, tide pools and open coasts. Juveniles form dense ball-shaped schools of about 100 fish; adults are solitary or occur in smaller groups of around 20 and are known to hide under ledges during the day (Ref. 1602, 5503, 12693, 37816, 48635). Adults search and stir the sand incessantly for crustaceans, mollusks, worms, and sometimes fish (Ref. 5213). Oviparous, with demersal eggs and planktonic larvae (Ref. 205). The highly venomous serrate spine of the first dorsal and each of the pectoral fins are dangerous, and even fatal in rare cases (Ref. 1602).
The male in the spawning pair constructs the nest under rocks and other large pieces of debris (Ref. 240). After spawning, the female departs while the male guards the eggs.
