Defensive Adaptations

They have bony, calcified skin, which protects them from most predators, and many wear striking colors that camouflage them or scare off potential attackers. Purely marine animals, there are no freshwater sea stars, and only a few live in brackish water.

How do sea stars help the environment?

Sea stars are important members of the marine environment and are considered a keystone species. A keystone species preys on animals that have no other natural predators and if they are removed from the environment, their prey will increase in number and may drive out other species.

How do starfish support and protect themselves?

To help protect themselves, these incredible invertebrates have evolved several effective defense mechanisms. As well as their tough, prickly, armor-like skin, some have striking colours that camouflage them amongst plants and coral, or scare off potential attackers.
