Sea Stars

Starfish, also known as sea stars, are not fish. They’re not stars either, but they have that distinctive star shape, with arms that can do amazing things. The arms can even be detached!

Starfish are invertebrate marine animals with fifteen-hundred species found in all of the world’s oceans from the tropics to the polar regions. Sea stars live from the seashore to 20,000 feet (6000 meters) below the surface. Most species have five arms, but some have more, and one Antarctic species has 50! The arms have tube feet that they use to move around on the bottom of the ocean to find food. The arms can detect the smell of food. If an arm senses food, it becomes dominant and pulls the sea star toward the food. The animal doesn’t have a brain to decide where to go.

Sea stars also “breathe” through their arms, taking in oxygen and removing carbon dioxide. Some species of starfish can regenerate a new arm when they lose one to a predator. They can shed their arms as a method of defense to escape a predator. Even more amazing is that some reproduce by shedding an arm and that arm then grows a body to become a new starfish.

The stars of the sea are not fish or stars, but they are another of the amazing creatures that show evidence of a Designer.
