Rays are flat, cartilaginous fish that belong to the same family as sharks. They are known for their unique, wing-like pectoral fins that allow them to glide gracefully through the water. Rays can be found in oceans and freshwater environments around the world, often hiding in sandy or muddy bottoms. Some common types of rays include the stingray and the manta ray. These fascinating creatures have a special way of hunting. Many rays use their electroreceptors to detect the electrical signals emitted by their prey, such as small fish and crustaceans. This ability helps them locate food even in murky waters, making them skilled predators in their underwater habitats.
