Although the relatively thin shell gives snails rather poor protection from determined or well-equipped predators, it does keep them from drying up when they seal themselves inside with the epiphram. The animal is similar in general form to the Turbinidae. The main adaptation strategy of sessile animals to prolonged air exposure is to slow down their metabolism and associated oxygen consumption; some animals (snails) can temporarily switch to anaerobic respiration [10]. If attacked by a predatory snail, it will climb on to the top of the predator's shell. Most species of aquatic snail have a comb-like gill.
