Habitat

The species is a bottom dwelling species that normally occurs between 90 m and 580 m in depth.

Other behaviours and adaptations

The Short-tail Torpedo Ray has electric organs in the disc. The organs are made up of hexagonal, fluid filled cells that cause the upper surface of the fish to have a positive charge and the lower surface a negative charge. Reports exist of fishermen who have received severe electric shocks from handling this fish.
