Habitat and Occurrence
The Giant Electric Ray, Narcine entemedor, has a broad distribution, inhabiting a range of marine environments. It is typically found in coastal waters and on the continental shelf, with a depth range extending from 1.0 to 100.0 meters. This adaptability allows it to thrive in a variety of habitats, including sandy bottoms, rocky reefs, and seagrass meadows. The Giant Electric Ray is often found in the epipelagic and mesopelagic zones, regions of the ocean that receive sunlight and are home to a diverse array of marine life.
Taxonomy
The Giant Electric Ray, Narcine entemedor, is classified within the Class: Elasmobranchii, which includes sharks, rays, and skates. It belongs to the Order: Torpediniformes, a group of rays that are characterized by their electric organs. Within this order, it is a member of the Family: Narcinidae, a family known for its species of electric rays, which are commonly found in tropical and subtropical waters around the world.
Feeding
The Giant Electric Ray, Narcine entemedor, is a carnivorous species that relies on a diet of invertebrates. Its primary food sources include sea squirts, sponges, and worms. It uses its electric organs to stun its prey, rendering it easier to capture and consume. This unique hunting strategy makes it an efficient predator in its environment.
