Over several generations, changes in genetic traits of birds' beaks have occurred. gill slits used for filter feeding. admin. Fish have gills that allow them to "breathe" oxygen in water.Water enters the mouth, passes over the gills, and exits the body through a special opening. Of the marine fishes, the greatest variety and volume live close to land in waters above the continental shelves that rim continents. One is the development of their nervous system, which is far more advanced . teeth to swallow their food whole.

Due to the lack of light even further below becomes a less important sense, and in many fish their eyes are considerably reduced, or even degenerate. Physical adaptations help an animal survive in its environment. Types of adaptations in animals and plants are categorized according to their function and the response observed. An adaptation is a feature that arose and was favored by natural selection for its current function. Behavior The actions of an animal. Camouflage A color or shape in an animal's body covering that helps it blend into its environment. Fish have adapted to their environment through the evolution of gills, swim bladders and fins. Some part of the animal's body, such as its size or shape, the body covering of the animal or the way the animal is moving, is structural adaptation. The cartilaginous fishes are jawed fish with paired fins, paired nostrils, scales, two-chambered hearts, and skeletons made of cartilage rather than bone.
