Scorpion Fish (Escorpora) / Red scorpionfish (Cabrachos)
Frequent stone or posidonia sea grass beds. The thorns on the head and dorsal are poisonous causing extreme pain. They are also difficult to capture.
Dogfish and Spiny Dogfish
A small shark usually captured by lure fishing. Has two poisonous thorns, one in front of each dorsal. The poison produces very painful wounds.
If fishing, you should always carry forceps / tweezers and protective gloves to remove the hook or cut the line without touching the fish. Once dead or even frozen, the poison can still be active and for this reason alone, they should always be returned to the sea.
If you are stung by a poisonous fish go straight to a doctor. They will apply the appropriate medication for the type of sting, so it helps to know what has stung you. Applying 50C+ of heat to the sting might help, but be careful not to burn yourself. This is normally achieved by placing the stung limb in hot water.
