Wolf eels also look more dangerous than they are. When provoked, they can produce a large tear-wound that can bleed a lot. If an eel is hooked while fishing, cut the line or use extreme care to prevent a severe bite. The fish have poison glands at the base of the fins. A sting from the spines inflicts an intensely painful, burning, throbbing pain, usually with swelling at the site.
Severe stings can result in nausea, vomiting, delirium, sweating, pale skin and shock.
The venom is destroyed by heat. The wounded area must be kept in hot water for 30-60 minutes. Call the Poison Center for more information. There are many species of jellyfish. They are usually almost colorless and therefore difficult to see.
