Longipedia
''Longipedia'' is a genus of marine copepods of the family Longipediidae, order Canuelloida. The genus ''Longipedia'' comprises 23 accepted species and is distributed worldwide. The Longipediidae generally are long and missile shaped, with segmented bodies covered by hard chitin. ''Longipedia'' utilize thoracopods to move, pulling themselves through the water. Distinctive features of ''Longipedia'' species are an elongated P2 endopod; and a tooth on the P2 endopod third segment. Identification and differentiation between ''Longipedia'' species can be difficult due to morphological similarities among species. Phylogeny Until recently the family Longipediidae was classified in the section Polyarthra of Harpacticoida. Recent genetic analysis has reclassified that section as a separate order, the Canuelloida. The morphological differences of the Polyarthra from the other Harpacticoids have also been identified as a reason for separation of Polyarthra from the other Harpacticoids ...

Polyarthra (crustacean)
Polyarthra is an order of copepods belonging to the class Copepoda.

Copepods
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some species are planktonic (inhabiting sea waters), some are benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult and then, after more molts, achieves adult development. The nauplius form is so ...
