Family Rajidae is a taxonomic classification that belongs to the order Rajiformes, commonly known as skates or in some cases, rays. It encompasses a diverse group of marine fish species that are mainly found in coastal waters and deeper oceanic regions across the globe. The Family Rajidae includes around 200 recognized species, making it one of the largest families within the Rajiformes order.
Members of the Family Rajidae are characterized by their flattened bodies, enlarged pectoral fins that resemble wings, and a long, whip-like tail. They possess a unique type of cartilaginous skeleton, lacking the bony structure found in many other fish families. Their skin is often rough, covered in small dermal denticles or scales that aid in protection.
These fish are predominantly bottom-dwellers, inhabiting sandy or muddy seabeds, rocky reefs, and kelp forests. They typically have a benthic lifestyle, spending most of their time resting on the ocean floor or partially buried in sediment, where they use their enlarged pectoral fins to propel themselves or glide effortlessly over the substrate.
Family Rajidae consists of various species, including the common skate, thornback ray, and the mottled skate, to name a few. They are primarily carnivorous, feeding on a variety of small invertebrates like crustaceans, mollusks, and small fish.
Many species within this family are commercially important, both as food sources and for their valuable skin, which is often used in the production of leather products. Additionally, skates and rays play a crucial role in marine ecosystems as they help regulate prey populations and serve as prey themselves for larger predators.
