The necessarily rapid processing rates limit the amount of time material may remain in the gut. Many deposit feeders have gut residence times of 30 minutes or less. Juvenile . can have gut residence times as low as 4 minutes (

Deposit feeders acquire food by ingesting large volumes of sediment and absorbing some fraction of the organic matter. Particle-associated microorganisms are generally absorbed well but are not abundant

Models of the feeding and behavior of deposit feeders are a recent addition to benthic ecology (e.g., Calow, 1975; Jumars et al., 1982; Levinton and Lopez, 1977; Taghon et al., 1978; Taghon, 1981). This chapter discusses models that fall under the general heading of optimal foraging theory.
