Wedgefish

Wedgefish are a group of rays in the order Rhinopristiformes, characterized by their shark-like appearance, particularly their flattened, wedge-shaped bodies and pointed snouts. They were formerly classified within the guitarfish family (Rhinobatidae), but are now recognized as belonging to their own family, Rhinidae.

Wedgefish inhabit tropical and subtropical coastal waters of the Indo-Pacific region. They are typically found in shallow habitats, including estuaries, bays, and coral reefs.

These rays are primarily bottom-dwelling creatures, feeding on crustaceans, mollusks, and small fish. They use their flattened bodies to glide along the seabed, and their electroreceptive ampullae of Lorenzini to detect prey hidden in the sand or mud.

Wedgefish are ovoviviparous, meaning the females retain the eggs internally until they hatch, giving birth to live young.

Several species of wedgefish are critically endangered due to overfishing, particularly for their fins, which are highly valued in the shark fin trade. Habitat degradation also poses a significant threat to their populations. Conservation efforts are underway to protect these unique and vulnerable rays.
