General Info

The electric ray belongs to the Torpedinidae family which comprises of two genera and 14 species. Their electric organ is formed of electro-plaques which stores electricity in tissues, similar to the workings of a battery. This electric organ is located on the side of the electric ray’s head and is kidney-shaped. Its shocks can be up to 220V strong. They are not very active creatures and hunt in groups by stunning their prey. They are ovoviviparous, thus their young are fully developed at birth from eggs.

Feeding

Electric rays feed on small fish and invertebrates.

Distribution

They can be found in temperate and tropical oceans across the world.
