It has been believed that marine crustacea do not encyst as adults. The benthic copepod Heteropsyllus nunni has been found to encyst in intertidal sands in the summer; free-living forms are abundant in the winter. A unique platelike structure on the cephalothorax is thought to be the site of cyst formation.
