}}Monstrilloida is an order of copepods with a cosmopolitan distribution in the world's oceans. The order contains a single family, Monstrillidae;[1] the family Thaumatopsyllidae was formerly included in the order, but is now usually placed in the Cyclopoida.[3] The taxonomy of the family is undergoing a period of revision,[4] although some necessary changes are apparent; for instance, the genus Strilloma is now considered a taxonomic synonym of Monstrilla, the largest genus.[5] The order is poorly known, biologically and ecologically, although the life cycle is known to differ from that of all other copepods.[6] The larvae are parasites of benthic polychaetes and gastropods, while the adults are planktonic and incapable of feeding, functioning solely to reproduce.[7] The family Monstrillidae is characterised by having a well-developed fourth pair of swimming legs, but a rudimentary or absent fifth pair. Adults have no oral appendages, and the mouth leads only to a short, blind pharynx. Females carry a long pair of spines to which the eggs are attached, while males have a "genital protuberance, which is provided with lappets"; in both sexes, the genitalia are very different from those of all other copepods.[8] References{{Portal|Crustaceans}}1. ^1 {{ITIS |id=88989 |taxon=Monstrilloida Sars, 1901 |accessdate=July 8, 2011}} {{plankton}}{{Taxonbar|from=Q3480154}}2. ^{{ITIS |id=88991 |taxon=Monstrillidae Dana, 1849 |accessdate=July 8, 2011}} 3. ^{{cite book |url=http://atiniui.nhm.org/pdfs/3839/3839.pdf |title=An Updated Classification of the Recent Crustacea |author=J.
