Indo-Pacific: Red Sea and East Africa to Samoa, north to southern Japan, southern Korea, and the Ogasawara Islands, south to Australia and Lord Howe Island. Palau and Yap in Micronesia (Ref. 1602). Sometimes enters freshwaters of East Africa (Lake Malawi) and Madagascar (Ref. 3879).

Biology     Glossary (e.g. epibenthic)

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).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00397 - 0.01666), b=3.00 (2.81 - 3.19), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.6 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.44-0.45; tm=1-3; tmax=7).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100) .
Price category (Ref. 80766):   Low.
