Many fish have spines with attached venom glands. When trodden upon, the spines of the marine Stonefish and the freshwater Bullrout penetrate deeply and deposit venom causing excruciating pain. General cardiovascular toxic effects can occur but are rare. Handling these or similar fish is also potentially dangerous.
The barbed spines on the tails of stingrays can inflict a serious gash or penetrating stab wound. Organs and blood vessels may be damaged, with the possibility of fragments of spines remaining in the wound. Injuries from these animals usually occur when the victim stand on an unseen fish, pulls a captured fish into a boat or swims to closely over a fish on the sea floor.
