Cat Fish

2/24/2014

All catfish, except members of Malapteruridae (electric catfish), possess a strong, hollow, bonified leading spine-like ray on their dorsal and pectoral fins. As a defense, these spines may be locked into place so that they stick outwards, which can inflict severe wounds.In several species catfish can use these fin rays to deliver a stinging protein if the fish is irritated.This venom is produced byglandular cells in the epidermal tissue covering the spines.In members of the family Plotosidae, and of the genus Heteropneustes, this protein is so strong it may hospitalize humans, those unfortunate enough to receive a sting; in Plotosus lineatus, the stings may result in death
