Starfish are famous for their ability to grow new limbs, and sometimes, entire bodies. Starfish eat clams, oysters, algea, fish, and sometimes starfish eat other starfish. They have tiny suction cups on their feet to help them catch their prey.
Sea stars have bony skin that keep them safe from most of the predators who might eat them. Many of them have bright or bold colors to help scare away attackers.
