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.

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.
Zebra Danio
The zebrafish is a small cyprinid native to South Asia's freshwater streams. Its distinctive blue-and-gold horizontal stripes and hardy nature make it a popular aquarium fish. It is also the most widely used vertebrate model organism in genetic research.
