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.

Question

Why is the occurrence of
eyelids in amphibians in
comparison to their absence in
fishes an adaptation to
terrestrial life?

Expert Solution

Step 1

Amphibians belong to the phylum Chordata. They are vertebrate tetrapods. This group includes frogs, caecilians, salamanders, and toads. The class Amphibia includes three clades, namely, Urodela, Anura, and Apoda.
