Catfish

Descrizione

Siluriformes, commonly known as catfish, are a diverse order of ray-finned fish characterized by prominent barbels resembling cat's whiskers. They inhabit a wide range of freshwater and some marine environments, exhibiting significant morphological and ecological diversity. This order includes species ranging from small, armored forms to large, predatory species, and they are found on every continent except Antarctica.

elongated

Colorazione

Highly variable; ranges from mottled browns and greens to silvery-grey, black, or even albino forms. Many species have cryptic coloration for camouflage.

terminal

Caratteristiche distintive

Presence of barbels (whiskers) around the mouth, typically 2-8 in number, used for chemoreception and foraging., Absence of scales (most species, though some have bony plates or scutes)., Adipose fin present in many families (a small, fleshy fin between the dorsal and caudal fins)., Often possess strong, serrated spines in the dorsal and pectoral fins, which can be venomous in some species.
