do bullheads sting?

Answer 1

I'm not sure if you can call it a sting, as in a bee sting. But yes, they have a bony spine on each front fin and another on their back. There is also a little poison there. I have been poked and it hurts like H*LL...for days. I've copied an article and supplied you with a link to read more about it.
============
Bullheads are probably best known for the sting that can result from careless handling. That "sting" is actually a sharp cut from contacting the sharp edges of the dorsal and pectoral fins. Jim Congdon, DNR fisheries manager in Horicon, says the fins are a defense mechanism the bullheads use to prosper in lakes and waterways throughout the state. "Predators learn to avoid a sharp-finned meal," he notes.

If you , like me, have had the unfortunate experience of swooping your hand into a mass of bullhead fry roaming near a boat landing, you understand how painful those sharp little fins can be. A bullhead "sting," is more painful than that of a bee, and within minutes swelling can occur. The pain can last for a week or more. Congdon explained that bullhead fry have small glands near their side fins which produce a poison that can make getting "finned" by even half-inch fry very painful. These poison glands are common throughout the catfish family. Not to worry though -- the poison is not life threatening and the pain can be dulled by dabbing the wound lightly with household ammonia. Don't dab gashes or larger open cuts.
