Electrical attack

The electric eel uses its shock to attack and paralyse its prey. The electric eel's attack shocks can measure up to 572 volts. The electric eel does not have strong colours that warn of its electricity.

Senses with electricity

The electric eel creates weak electric fields of about 50 volts to orient itself. In this way, it gains an overview of its surroundings and checks for nearby prey by sensing distortions in the field.

A battery tail

The electric eel's tail acts as one large battery and represents 90% of the eel's length. Thousands of small cells are located in the tail, each of which generates a tiny charge of electricity. Together they produce the electric eel's shock.
