During this time, metabolism slows and the snails live in a suspended state until warm rains revive them. In some Spanish-speaking parts of the Caribbean, when used as a food source Cittarium pica is known as bulgao, or simply as caracoles (snails, in Spanish). 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].
