The evolution of different body plans in animals has led to a wide diversity of species. For example, in Cnidaria (which includes jellyfish and corals) we see a radically different body plan compared to insects or birds. What significant evolutionary development is exhibited by insects and birds that is not present in Cnidaria? The development of bilateral symmetry and cephalization. The development of radial symmetry. The development of a calcified exoskeleton. The development of tentacles for capturing prey. 666

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

The evolution of different body plans in animals has led to a wide diversity of species. For example,

not present in Cnidaria?
The development of bilateral symmetry and cephalization.
The development of radial symmetry.
The development of a calcified exoskeleton.
The development of tentacles for capturing prey.
