Fun Fact(s):
Considered a delicacy in parts of range & flesh is not poisonous.
When disturbed, they’ll raise feathery fins as warning & flee if given chance. If cornered, they’ll charge.
Dorsal/anal/pelvic fins have highly venomous spines used in defense. These spines cause extremely painful stings/puncture wounds lasting for hours to even days. Effects of venom are throbbing pain, swelling, bleeding, numbness, redness, bruising, skin discoloration, respiratory distress, nausea, & vomiting. Deaths have occurred from stings from these fish. Venom is neurotoxic.
These fish can sting even if dead.
Stings to people usually occur because someone was handling it.
