Cuisine & Edibility
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.

Lean, dense flesh with a clean, meaty flavor; prized for sashimi and poke. Excellent seared rare, grilled as steaks, or served raw; one of the most commercially valued tunas.
Species Overview
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.
Yellowfin Tuna
The yellowfin tuna is a pelagic predator found in tropical and subtropical oceans worldwide. Capable of speeds exceeding 75 km/h, it is prized both as a sport fish and for its high-quality sashimi-grade flesh.
