Final answer:
Sea stars have the ability to flip themselves back over by using their tube feet and muscular contractions.
Step-by-step explanation:
Sea stars, also known as starfish, have the ability to flip themselves back over if they end up upside down. This is due to their unique body plan and structure. Sea stars have a water vascular system that helps them with movement and orientation. In order to flip themselves back over, they use their tube feet and a combination of muscular contractions to create enough force to push themselves upright again.
For example, if a sea star ends up upside down, it will begin by extending its tube feet and attaching them to its surroundings. It will then contract its muscles to create tension, and release it suddenly, causing its body to flip and right itself. This process can take varying amounts of time depending on the size and species of the sea star.
