does the sea cucumber needs much light to survive?

Answer 1

Sea cucumbers do not require much light to survive, as they primarily inhabit the ocean floor in dark environments such as coral reefs and deep-sea habitats. They are detritivores, feeding on organic matter that settles on the seabed, rather than relying on photosynthesis like many other marine organisms. While some species may encounter light in shallow waters, their survival is not dependent on it.
