Short description

Generally brown to black in color; pelvic fins separate rather than fused into a disc; young fish <2.5 cm long are distinctively jet black on the upper body and lighter on the sides and belly (Ref. 44091).

Found in both altered and unaltered streams, but being unable to climb waterfalls restricts its habitat to the lower reaches of streams and estuaries; can be observed darting into the mud and leaf litter, or sheltering among rocks and cobble, rarely showing in the open; highly predaceous on various invertebrates, e.g. slow-moving thiarid snails and asiatic clams, and fishes; traditionally caught with a baited hook attached to a short stick (fishing method called kiomo'omo); relished as a food item, particularly when wrapped with leaves and roasted; now prized as bait by near-shore papio fisherman (Ref. 44091).
