The flesh of the barracuda sometimes carries the toxin ciguatera, although it is regularly eaten by humans. Symptoms of ciguatera poisoning include nausea, vomiting and diarrhea. Neurological symptoms, such as headaches, paresthesia and vertigo, often follow. Scarce treatment options exist for ciguatera poisoning, although recovery is possible in time.
The barracuda is a tropical and subtropical oceanic ray-finned fish. Its body closely resembles that of a freshwater pike, and the barracuda's powerful jaws and sharp teeth are used to tear flesh or simply bite the prey in half. The barracuda primarily hunts fish in addition to scavenging. Although the barracuda has a fearsome reputation, it is unlikely to bite humans.
