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).
Description: Characterized by black to brown color on upper side; white ventrally; pair of narrow white stripes extending from head to caudal fin; well separated dorsal fins; origin of second dorsal fin posterior to level of pelvic fin origin; depth of body 5.8-8.0 in SL; anterior nostril tubular, dorsal to upper lip; gill membranes narrowly attached across isthmus (Ref. 90102). |
| 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). |
