Sea urchins live in marine communities that include a variety of species living in close proximity. Most of these species, including sea urchins, have external fertilization, a reproductive strategy that potentially has a low probability of sperm and egg contact. List several adaptations of sea urchins that help ensure successful reproduction. Explain.

Evolutionary adaptations

Evolutionary adaptation is the process through which organisms adapt or adjust to their surroundings to increase the chances of survival, mating, and reproduction. An organism's behavior, physiology, and structure are adjusted or changed to make it more suited to its environment.
