Adaptations - Fish


Fishes have been swimming and reproducing for over 450 million years on Earth. During this time, fishes have undergone changes that help them live better in some water habitats than in others. This is a common theme in biology. Organisms change over time as some features are favored more than others for survival. With so many different types of environments to live in, fish have diversified into many different body plans.
