And the brother and sister both making sure their voices are heard!
Now...what is he talking about!?!???!
Catfish have no scales; their bodies are either naked or covered in bony plates. They may have up to four pairs of barbels: nasal, maxillary (on each side of mouth), and two pairs of chin barbels, although pairs of barbels may be absent, depending on the species. Because their barbels are more important in detecting food, the eyes on catfish are generally small. [1]
All catfish, except members of Malapteruridae (electric catfish), possess a strong, hollow, bonified leading spine-like ray on their dorsal and pectoral fins. These rays may be locked into place so that they stick outwards as a defense. In several species catfish can use these fin rays to deliver a stinging protein if the fish is irritated.[4] This poison is produced by glandular cells in the epidermal tissue covering the spines.[1] In members of the family Plotosidae, and of the genus Heteropneustes, this protein is so strong it may hospitalize humans unfortunate enough to receive a sting. In many catfish, these fins may be held open and locked in place.
