9. The Electric Ray:
This type of fish lives at the seabed. There are four families with 69 species of the electric ray fish. This type of fish has no bones, the whole body is cartilaginous. Their pectoral fins are large and give the fish a flattened appearance. These electric rays produce electric currents in their bodies. The amount of electricity differs depending on the species of the ray fish. However, the minimum is 8 volts while the maximum is 220 volts.
The ray fish uses the electricity as a means of protection against predators. It also uses it to attack the prey. If you happen to touch a live ray fish or step on it, you will receive an electric shock. It is, therefore advisable for deep sea divers to be extra careful to avoid injury or death.
