The oceans are home to many ray species. Some are more familiar than others. Stingrays are found almost anywhere in shallow beach waters, and manta rays can grow to enormous sizes. Most rays have a stinger, which they use to defend against predators or attackers. Steve Irwin, the Australian conservationist, was killed while swimming next to a large manta ray. Rays are generally slow swimmers, so their stingers serve as their main defense. A lesser-known group of rays that don’t use stingers is the electric rays, also called torpedo fish.
Larger electric rays can generate an electric shock of up to 220 volts. That’s enough to electrocute their prey or stun an adult human. Researchers have observed a large white shark approach an electric ray and turn away when it came too close. Electric rays primarily use their electric power to capture prey while hiding beneath the ocean floor, waiting for prey to swim by.
God has equipped all living things with survival and defense mechanisms. Some can run at high speeds, others use camouflage, and some have venom or toxins. Electric rays are among the few that use high-voltage electricity. The variety of designs in living things shows evidence of a Designer.
