Cuisine & Edibility
Cobia
Firm, moist white flesh with a mild, buttery flavor; moderate fat and large, clean flakes. Extremely versatile — excellent grilled, smoked, raw as sashimi, or used in ceviche.
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
Cobia
The cobia is a powerful pelagic fish that often follows large rays, sharks, and turtles. Its flattened head and elongated body resemble a shark. Excellent table fare with firm, white flesh, it is increasingly farmed in aquaculture.
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.
