This Is What Peak Crustacean Looks Like

The video explores the concept of carcinization, where crustaceans evolve a crab-like form through convergent evolution. This body shape has evolved multiple times due to its advantages, such as protecting the pleon, enhancing mobility, and reducing energy needs. True crabs belong to the suborder Brachyura, while many crab-like species are not true crabs due to different evolutionary paths. The video also discusses the evolutionary journey of crab-like forms in the Annamura group and highlights convergent evolution in other species.
