Fish bodies vary with the habitat the fish live in as well as the needs that the fish have. bottom-dwelling fish are often flattened and camouflaged. open-water predators often have large mouths and bullet-shaped bodies. reef-dwelling fish are often shaped like rudders for fast swimming and have small mouths for grazing. schooling fish that eat plankton are often streamlined and bullet-shaped with large toothless mouths.
