How do starfish maintain homeostasis?

Answer 1

Starfish maintain homeostasis primarily through their water vascular system, which helps regulate internal pressure and facilitates movement and feeding. They rely on a network of canals filled with seawater to control their tube feet, enabling them to adapt to changes in their environment. Additionally, starfish can regulate their internal salt concentration by selectively absorbing or expelling water through their tube feet and body surface, helping them balance their osmotic pressure in varying salinity levels.
