Batoidea is a subclass of cartilaginous fish that includes rays and skates. These creatures are characterized by their flattened bodies and wide pectoral fins, which they use to glide gracefully through the water. Batoidea are primarily found in marine environments, although some species inhabit freshwater. These fish are known for their unique feeding habits, often using their specialized mouths to consume benthic organisms like mollusks and crustaceans. Batoidea are closely related to sharks, sharing a common ancestor, and are part of the larger class Chondrichthyes, which includes all cartilaginous fish.
