Natural Selection in Blue Crabs
Through natural selection, blue crabs have developed sharper claws to help them tear food easily and higher appendages that have allowed them to be better swimmers. The blue crabs have also adapted protein shells, which have allowed their bodies to become lighter so that they can move alot faster. Lastly, another adaptation through natural selection is an open circulatory system which allows the nutrients to go directly to their tissues.
