Suggest why marine organisms living in polar regions have a very high proportion of cholestrol in their membranes?

hmm thats a hard one, but i knw that cholesterol keeps the cell not to firm and not too fluid, so mayb the cold has something to do with the firmess of the cell??

isnt it to do with like.. umm how fat layers/lipid keeps the warmth in?

Cholesterol in the Plasma membrane increases fluidity and so stops the membrane from freeing and fracturing around from around the living cell. (It basically acts as a membrane anti-freeze).

Hope this helps
