What do starfishes legs do?

Starfish don't have legs in the traditional sense. They have arms, and these arms do a lot more than just walk!

Here's what starfish arms do:

* Movement: Starfish use their arms to move around. They have hundreds of tiny, tube-like feet called tube feet on their undersides. These feet work like suction cups, allowing the starfish to crawl along the seafloor.

* Feeding: Some starfish use their arms to pry open clams and other bivalves. They then push their stomach out of their mouth, into the shell, and digest the animal's soft tissues.

* Sensory: Starfish have sensory cells on their arms that help them sense their environment, including changes in light, temperature, and water currents.

* Regeneration: One of the most amazing things about starfish is their ability to regenerate lost limbs. If a predator bites off an arm, the starfish can grow a new one.

So, while starfish don't have legs, their arms are incredibly important for their survival and allow them to perform many different functions.
