If ‘why’ implies purpose, then the main purpose of having gall bladder – digestion of lipids – is not needed in rats, because their diet has very little fat. Furthermore, the bile juice, secreted from the rat’s liver is highly concentrated, an therefore a gall bladder is not necessary.Since the size of the gallbladder must be proportional to the size of the liver, the gallbladder may be absent in big mammals (elephants, rhinoceros, whales) because of their anatomical peculiarities (2). In these mammals there is a considerable synthesis of bile alcohols, which are poorly solubilize cholesterol (2).Animals like felines and canines, which take in food in intervals, require a large amount of bile acid at once, so a gallbladder is developed in their anatomy. However, animals that eat frequently, without long intervals, constantly need bile acids, so an organ to store the acids is unnecessary.
