Cuisine & Edibility
Angelfish

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
Angelfish
The freshwater angelfish is a majestic cichlid with a laterally compressed body and long, flowing dorsal and anal fins. Native to the Amazon basin, it has been selectively bred into numerous color varieties including marble, koi, and platinum.
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.
