Summary
The larvae, called veligers, emerge within 3 to 5 days and are free-swimming for up to a month. Veligers are microscopic in size (0.04 -0.07mm) and can be found in densities of 500,000 per cubic meter. Optimal temperatures for larval development range from 68-72°F. Under the right environmental conditions, the veligers can survive 3-5 days in moist conditions.
