Cuisine & Edibility

Atlantic Bluefin Tuna

The pinnacle of raw fish dining — intensely rich, fatty tuna-o-toro with deep red color and buttery, umami-forward flavor. Commands the highest prices globally in Japanese sushi markets.

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

Atlantic Bluefin Tuna

The Atlantic bluefin tuna is one of the largest bony fish, capable of crossing the Atlantic in under 60 days. A single specimen has sold for over $3 million at Tokyo's fish market. It can maintain a body temperature above the surrounding water.

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.
