Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.
