Cuisine & Edibility
Electric Eel
Not consumed — an ornamental and scientific novelty species kept in specialized aquarium exhibits; edible in principle but extremely dangerous to handle due to powerful electric discharge.
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
Electric Eel
Despite its name, the electric eel is not a true eel but a knifefish. It can generate electrical discharges of up to 860 volts to stun prey and defend itself. About 80% of its body is dedicated to three electric organs.
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.
