position under his body until the female molts. When the female's shell is still soft the male will invert her to position themselves with their abdomens in contact together. The male then transfers his spermatophores to her gonopores. Once mating has occurred, the eggs will spawn around fifty-seven days later and will have an fecundity between 135,000 and 680,000.

The crabs can be found from
Massachusetts, U.S. to areas in Argentina. They are common in shallow water on sand in ocean beaches, but can be found in depths up to two hundred feet (61 m) deep. They are typically found in temperate or tropical waters between eleven and twenty-nine degrees Celsius

Speckled swimming crab eggs around eighteen days and will grow into the first stage of crab thirteen days later. The average age for a Speckled swimming crab is two years.
