What Do Sea Stars Eat?

Sea stars, also known as starfish, are fascinating creatures that can be found in oceans all over the world. They come in a variety of shapes, sizes, and colors, and have the ability to regenerate their limbs if they are injured or lost. But have you ever wondered what sea stars eat? Let’s delve into their feeding habits and discover what keeps these marine organisms nourished.

Sea stars are carnivorous predators, and they have a unique feeding mechanism. They have a specialized stomach called a cardiac stomach, which they can extend out of their mouth to engulf and digest their prey. Some sea stars feed on algae, while others prey on small invertebrates such as mussels, clams, and snails. They use their tube feet to pry open the shells of their prey and then push their stomach inside to extract the soft tissues.
