Cuisine & Edibility
Dwarf Gourami
Not consumed — popular ornamental labyrinth fish treasured in freshwater aquariums for its vivid red-and-blue striped coloration and calm temperament.
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
Dwarf Gourami
The dwarf gourami is a brightly colored labyrinth fish native to the slow-moving waters of South Asia. Males build elaborate bubble nests at the surface for spawning. Its pelvic fins have evolved into long, thread-like feelers used to sense the environment.
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.
