In the different lineages of molluscs, it is easy to understand the variations from the basic organizational plan in relation to the lifestyles of the organisms. For example, the clam is a buried living organism that feeds by filtration and the cuttlefish is a free predatory organism. The organization of Lamellibranchs and Cephalopods can then be related to these lifestyles. ndicate in a short text : Adaptations to predation in cuttlefish (and by extension in cephalopods)

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.
