Sleeper Rays [Hypnidae]

Description

Hypnidae, or sleeper rays, are a family of electric rays known for their sluggish behavior and preference for staying buried under the sand for most of the time, which gives them their common name. They have a unique appearance with a smooth, rounded body and large, oval pectoral fins that extend around the body, giving them a distinctive silhouette. Sleeper rays are found in temperate to tropical waters, typically on sandy or muddy bottoms. They possess electric organs that are used for defense and to capture prey, although they are generally considered less active hunters compared to other electric rays. Their diet mainly consists of small fish and crustaceans.
