Animal Strategies for Getting Food

One variable related to the structure of digestive systems is whether an animal is a continuous or discontinuous feeder. Many continuous feeders are slow-moving or completely sessile animals (they remain permanently in one place).
Discontinuous feeders tend to be active, sometimes highly mobile, animals.
Typically, discontinuous feeders have more digestive specializations than continuous feeders because discontinuous feeders take in large meals that must be either ground up or stored, or both.
