Catfishes are a group of fish with ray fin, categorized under the order nematognathi or Siluriformes. The name catfish originates from their conspicuous barbels which have a striking resemblance to cat's whiskers.
They range in size and behavioral displays from the Mekong giant catfish( southeast Asia), wels catfish (Eurasia and the Paraiba in south America), to species that feed on dead matters on the bottom (detrivores), and the tiny parasitic species known as candiru, Vandellia cirrhosa.
They come in different types, the naked ones without scales and those that are armor plated. And so, for most people killing a catfish is not so easy a task. Hence, everyone wants to figure out the easy way of "how to kill a catfish".
Despite their nomenclature, not all of them have prominent barbel. Catfish of the order Siluriformes have distinct features of the swim bladder and skull.
