Cuisine & Edibility
Atlantic Cod
Iconic mild white flesh, low fat, and a flaky texture; the backbone of fish-and-chips and salt cod traditions worldwide. Currently Vulnerable; sustainable sourcing is strongly recommended.
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 Cod
The Atlantic cod is one of the most historically important commercial fish species. Its mild, flaky white flesh has been a staple food in Europe for centuries. Overfishing caused the collapse of the Grand Banks fishery in 1992.
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.
