No, starfish do not need sunlight to survive. They are able to survive in a range of light conditions, as they primarily rely on capturing prey for food and obtain oxygen through their tube feet.
Starfish filter sea water to extract nutrients and oxygen. They use their tube feet and specialized structures called podia to create water currents that bring in food particles and oxygen from the water for them to consume. This feeding behavior helps them survive and grow.
They have two stomachs because the cardiac is the one who uses its stomach to extend, so it can grab their prey, and the pyloric is the one who digest the food which it passes through the stomach, to the suckers and digest it on the outside with the suckers.
