Pataecus

Pataecus is a genus of fish in the family Pataecidae, commonly known as “slipper skates” or “false skates.” They are cartilaginous fish that are closely related to skates (Rajiformes) but have some distinctive characteristics that separate them as a distinct group.

Common Names

Common names for species in the genus Pataecus include slipper skates, false skates, and the more specific names such as the "longnose skate," "broadnose skate," or "smooth skate" depending on the specific species.

Characteristics

Pataecus species exhibit several unique characteristics. They are generally smaller in size than typical skates, with most species reaching a maximum length of around 50 centimeters (20 inches). They have a flattened, oval-shaped body, with a wide, rounded pectoral fin that extends around the head. A key distinguishing feature is the presence of a pair of slender, fleshy appendages called "cephalic lobes" located on the head, which are thought to be used for sensing prey. Pataecus species also have a long, whip-like tail with a small dorsal fin and a rudimentary caudal fin.

Environments

Slipper skates inhabit the deep-sea environments of the Atlantic, Pacific, and Indian Oceans. They prefer muddy or sandy bottoms, and can be found at depths ranging from a few hundred meters to over 2,000 meters. They are benthic feeders, meaning they feed on organisms that live on or in the seabed.
