Cuisine & Edibility

オニカマス

Firm, lean white flesh with a mild flavor when small; larger individuals risk ciguatera fish poisoning and are generally avoided. Smaller fish eaten grilled or fried in the Caribbean.

Great Hammerhead Shark

Critically Endangered — consumption strongly discouraged. Fins are historically traded but the species faces severe population decline; eating this fish is ecologically irresponsible.

Species Overview

オニカマス

The great barracuda is a fearsome-looking predator found in tropical and subtropical oceans. With its torpedo-shaped body, pronounced underbite, and fang-like teeth, it can strike prey at speeds exceeding 58 km/h.

Great Hammerhead Shark

The great hammerhead is the largest of the nine hammerhead shark species. Its distinctive cephalofoil (hammer-shaped head) houses an array of electroreceptors that allow it to detect stingrays buried beneath the sand.
