Descrição breve

Espinhos dorsais (total): 0. Moderately long barbels, nasoral grooves present but no perinasal grooves, mouth well in front of eyes, spiracles minute, precaudal tail shorter than head and body, dorsal fins broadly rounded (the first much larger than the second and anal fins), caudal fin moderately long, over 1/4 of total length, yellow-brown to grey-brown in color, with or without small dark spots and obscure dorsal saddle markings (Ref. 247). Head blunt, mouth inferior, pair of conspicuous barbels between nostrils (Ref. 26938).

Biologia     Glossário (ex. epibenthic)

Found on continental and insular shelves. Solitary (Ref. 26340) and sluggish fish, often encountered lying on the bottom (Ref. 9987). Nocturnal, feeding on bottom invertebrates such as spiny lobsters, shrimps, crabs, sea urchins, squids, octopi, snails and bivalves, and fishes like catfishes, mullets, puffers and stingrays. Ovoviviparous with 21 to 28 young in a litter (Ref. 9987, 43278). Kept in captivity for researches. May attack humans if they are molested or stepped upon accidentally. Edible, but mainly valued for its hide, which makes extremely tough and durable leather (Ref. 9987). Common over shallow sand flats, in channels, and around coral reefs; young may be found among prop roots of red mangroves (Ref. 26938).
