The smoothnose wedgefish (Rhynchobatus laevis) is a species of fish in the Rhinidae family. It is found in northern Indian Ocean and northwestern Pacific Ocean, ranging from the Arabian Sea and Persian Gulf east to Bangladesh, and South China Sea to southern Japan.[1] Populations elsewhere are now recognized as separate species.[2] Its natural habitat is shallow coastal seas and off the mouths of rivers.[1] It is threatened by habitat loss and overfishing.[3]
