Why are amazon cat fish dangerous

Answer 1

All catfish, except members of Malapteruridae (electric catfish), possess a strong, hollow, bony 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.[6] In several species catfish can use these fin rays to deliver a stinging protein if the fish is irritated.[21]This venom is produced by glandularcells in the epidermal tissue covering the spines.[5] In members of the family Plotosidae, and of the genus Heteropneustes, this protein is so strong it may hospitalize humans who are unfortunate enough to receive a sting; in Plotosus lineatus, the stings may result in death.
