Full Answer

Stingrays spend a great deal of time on the ocean floor, partially covered by sand or mud. Because their coloring is so similar to the colors of the ocean floor, they are well camouflaged. This allows them to avoid predators and wait for potential prey to pass. Rather than using their eyes to detect prey, stingrays rely on electrical sensors around their mouths called ampullae of Lorenzini. These organs sense the electrical charges surrounding the potential prey.

    How do stingrays reproduce?

    A:

    Stingrays fertilize internally via sexual intercourse. During mating, the male stingray bites the female’s disc, which enables him to insert his clasper, or modified pelvic fin, into the female’s cloaca. The clasper then transfers the sperm into the female’s oviduct. The female stingray gives birth to live young.
