Members of the Rhinobatinae are mostly found in warm-temperate to tropical inshore continental water around the world. There are 6 genera and 48 species worldwide. They often occur off sandy beaches, in muddy enclosed bays, in estuaries, and off river mouths. These fishes are strong but slow swimmers. They are commonly found near the bottom but often swimming well above it or near the surface. All species are live-bearing. They feed on benthic invertebrates and are inoffensive to human.
