Yes, a catfish can fin you. 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. However, despite all these risks, catfish finning is not usually fatal. Although there are a few cases of large catfish stabbing into a heart with their spines. Some smaller species of catfish's venom are fatal, such as the Striped Eel Catfish. Smaller and/or marine catfish tend to have more virulent stings, where as larger freshwater catfish tend to cause extreme pain and swelling.
They're fins have some sort of sharpness..... They don't have teeth though...
