The marbled electric ray is a marine fish with a flat disk-shaped body. It generates electric discharges to stun prey and defend itself.
The marbled electric ray differs from other rays with its bright marbled pattern and powerful electric organs. It is important for marine nature because it regulates the population of small animals on the seabed.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
