WedgefishRhinidae

Wedgefishes (Rhinidae) are large, shark-like rays. They possess a distinctive flattened head and pectoral disc, which merges smoothly into a robust, shark-like body. This body is equipped with two prominent dorsal fins and a strong, crescent-shaped caudal fin. Body coloration ranges from grey to olive-brown, often marked with pale spots or darker bars, varying between species. Members of this group can grow to lengths exceeding 3 metres (10 feet).

These rays inhabit sandy or muddy substrates adjacent to reef structures and channels, typically found from shallow depths down to 100 metres (330 feet). Wedgefishes primarily feed on benthic invertebrates such as crabs, shrimp, and bivalves, supplemented by small bottom-dwelling fish. Unlike most rays, they propel themselves through the water by undulating their entire body and tail, rather than flapping their pectoral fins. They are often observed resting motionless on the seabed, sometimes partially buried in sand, and generally exhibit shy behaviour.
