Emerita has a barrel shaped body. It has a tough exoskeleton and can hold its appendages close to the body, allowing it to roll in the tidal currents and waves. It has feathery antennae, which are used to filter plankton and detritus from the swash.

The genus as a whole has a broad distribution in tropical and subtropical regions. Most individual species, however, are restricted to smaller areas, and their ranges rarely overlap. The genus is common on both coasts of the United States and along the Atlantic coast of Africa; the related genus Hippa is found across the Indo Pacific, including Australia.

Twelve species are recognised: The type species is Cancer emeritus (now E. emeritus), because at one time, it was the only species in the genus.

Emerita is adept at burrowing, and is capable of burying itself completely in 1.5 seconds. During this action, the carapace is pressed into the sand as anchorage for the digging limbs. Seabirds also eat Emerita, but do not appear to target the aggregations of mole crabs. In Malaysia, the sand crab locally known as yat yat, ibu remis, kutu laut or udang pasir can be found along the beaches in Kelantan during the monsoon season. The crab is a local delicacy that is usually fried with eggs or roasted on a skewer like satay.

Emerita has a short lifespan, perhaps no more than two to three years, and can reproduce in its first year of life.
