Abstract The life history pattern, behavior, and distribution of the mysid crustacean,Heteromysis formosa, was studied in a temperate salt marsh. This mysid occurred in epibenthic sled collections every month, but was most abundant from June through November. Marsh creeks with irregular bottoms supported the largest populations, although some individuals occurred in other estuarine habitats and shallow ocean areas.Heteromysis formosa remains hidden on the bottom during the day and swims over open bottom at night. Many young fishes feed onH. formosa, especially at night. Seasonal changes in mysid abundance were related to the life history pattern. Reproduction was continuous from April through October. Overwintering populations of immature mysids were small. FemaleH. formosa were capable of reproducing more than one time. The number of young per brood ranged from 7 to 32 and was related to total adult body length.
