As such, in the case of a more active lifestyle, the sand shrimp may compensate by altering its diet into a more carnivorous feeding and selectively consume animal tissues, which provide higher energy content.

According to an observation of the populations in Mystic River estuary, this is categorized into one in early spring and one in late autumn.

In early spring, mature sand shrimps that are two or three year old immigrate from its regular habitat offshore and into shallow shorelines, where they will then mate and reproduce.

This immigration pattern works as a recruitment mechanism within the life history of mature sand shrimps.

Temperatures play a crucial factor as it not only determines the length of larval life, but also the species' growth in differing habitats.

However, they have a preference that includes brine shrimp, clam, and hard-boiled egg or Baker's yeast—although it's mostly animal tissues of marine origins—and grow best on these diets.
