There are 5 species of stonefish that can be found in the coastal regions of Indian and Pacific oceans. Some species of stonefish live in the rivers. Stonefish lives close to coral reefs and underwater rocks. It often lies buried in the sand in the shallow water.
While kingfishers are usually thought to live near rivers and eat fish, most of the kingfisher species in the world live away from water and eat small invertebrates. Like other members of their order they nest in cavities, usually tunnels dug into the natural or artificial banks in the ground.A quarter of all kingfishers nest in disused termite nests. A few species, principally insular forms, are threatened with extinction.hey have a cosmopolitan distribution, with most species found outside of the Americas. The group is treated either as a single family, Alcedinidae, or as a suborder Alcedines containing three families, Alcedinidae (river kingfishers), Halcyonidae (tree kingfishers), and Cerylidae (water kingfishers).
