Morphology: Sea stars have a star-shaped body with penta-radial symmetry. Its color varies from orange to purple.The body has a central disc in which arms come out of.
Adaptations: They have calcified skin to protect them from predators.
Many sea stars wear different types of color to camouflage them or scare off the predator.

Importance: Scientists call starfish a keystone species in marine biology, because the number and the presence of starfishes in the oceans can greatly affect other animals and creatures in the sea. Starfish are general predators and this means a lot of its species can eat whatever they want as long as they can catch it. The wide range of prey that starfishes can eat is one of the reasons why it is helpful in creating balance in marine biodiversity. These animals are keys in keeping resources and space in the sea balanced.
