Description synthétique Morphologie | Morphométrie

Rayons mous anaux: 22 - 28. Maxillary barbels, first ray of dorsal fin, and first ray of pectoral fin extended as long, flat filaments. 1 pair of barbels on chin.

Biologie     Glossaire (ex. epibenthic)

Mainly marine but enters brackish estuaries with relatively high salinities (Ref. 5217). Opportunistic feeders over mud and sandy bottoms (Ref. 27549). Feeds mainly on small fishes and invertebrates. The dorsal and pectoral fins are equipped with a serrated erectile spine, both of which are venomous. Commonly caught by anglers along bridges, piers and catwalks. Flesh considered good; marketed fresh (Ref. 5217). Minimum depth reported taken from Ref. 57178.

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Each male carries not more than 50 eggs in its mouth, usually averaging from 15 to 30 (Ref. 205).
