I have however been finned by a catfish.
The two pectoral fins and dorsal fin have long, hooked spines that dig into skin, excreting venom that may produce extreme pain, necrosis and vasoconstriction (Tightening of the blood vessels). The vasoconstriction is present to slow down the speed at which the venom moves, thus enabling it to be more concentrated and potent. Also, catfish fins house bacteria, and a high risk of infection is present.
