Cuisine & Edibility
Atlantic Bluefin Tuna
The pinnacle of raw fish dining — intensely rich, fatty tuna-o-toro with deep red color and buttery, umami-forward flavor. Commands the highest prices globally in Japanese sushi markets.
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.
Species Overview
Atlantic Bluefin Tuna
The Atlantic bluefin tuna is one of the largest bony fish, capable of crossing the Atlantic in under 60 days. A single specimen has sold for over $3 million at Tokyo's fish market. It can maintain a body temperature above the surrounding water.
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.
