Facts about Electric Ray
- 08
Most electric ray species mature slowly, not reaching sexual maturity until 3 to 5 years of age, limiting their reproductive rate compared to other marine fish.
- 07
Venomous spines covering the tail of electric rays deliver toxins that work synergistically with electrical shocks to incapacitate prey and deter predators.
- 06
Females of most electric ray species give birth to live young rather than laying eggs, with gestation periods lasting several months before producing litters of up to 15 offspring.
- 05
Flattened bodies and sedentary lifestyles allow electric rays to remain motionless on the ocean floor for hours while waiting to ambush passing fish and crustaceans.
- 04
Electric rays use their electrical organs to detect prey buried in sand through a process called electroreception, sensing electrical fields as weak as five microvolts per centimeter.
- 03
Approximately 70 species of electric rays inhabit ocean floors worldwide, ranging from shallow coastal waters to depths exceeding 1,000 meters in the Atlantic, Pacific, and Indian Oceans.
- 02
Numbfish, another name for the electric ray, was documented by ancient Greek physician Hippocrates around 400 BCE as a medical treatment for pain and paralysis.
- 01
The electric ray can generate up to 220 volts of electrical discharge from specialized organs called electroplaques located in its head and body.
