A bladderskate is a type of fish belonging to the family of skate, specifically the genus Bathyraja. These fish are characterized by their flattened bodies and wing-like pectoral fins, which allow them to glide over the ocean floor. Bladderskates are typically found in deep-sea environments and are known for their unique adaptations to their habitat. They are less commonly encountered than other skate species due to their deep-water lifestyle.
