	Anostracans swim by moving their phyllopodia (leg like appendages on the thorax segments). When swimming, fairy shrimp will have their ventral side facing upward, which is why it is said that they are "swimming upside-down" [3]. While swimming, they filter food indiscriminately from the water and scrape algae and other organic materials from solid surfaces, pressing said ventral side against the food source [5].

	Fairy shrimp are characterized by their ability to enter diapause, which is a state of dormancy where all growth and metabolism pause, as an egg (or cyst) [4]. This is an especially important biological trait because it assists in both species' dispersal and overcoming difficult environmental conditions. The Fairy shrimp cyst can withstand conditions anywhere from UV radiation, to droughts, frosts, hyper salinity, and even the vacuum of space. Diapause is also how fairy shrimp to colonize new habitats. This movement is facilitated by a variety of conditions such as predators, wind, and currents within water as the adults are unable to leave the freshwater system [4].

	Members of this order, most notably brine shrimp, are used as food for ~~fish and~~ other [[organisms]] in ~~aquaria and~~ aquaculture. In natural environments they are also eaten by birds, water boatmen, ~~fishes~~ and other crustaceans.

	===Thorax and Abdomen===		===Thorax and Abdomen===
	Most members of this order have a thorax with 13 segments with the exception of ''Polyartemiella'' and ''Polyartemia'' which possess 19 and 21 segments respectively. All segments but the last two are similar in that they have a pair of flattened leaf-like appendages [1]. The last two segments of the body ~~are fused together and the~~ appendages ~~are then specialized~~ for sexual reproduction. Most fairy shrimp reproduce sexually, however a few reproduce by parthenogenesis. The abdomen ~~is comprised of~~ 6 segments ~~without~~ appendages, and a telson, which bears two flattened cercopods~~. Anostraca can be found with 10, 11, 17, or 19 pairs of legs across their thorax, depending on the species [11]~~.

Each segment houses a pair of legs. All segments but the last two are similar in that they have a pair of flattened leaf-like appendages [1]. The last two segments of the body contain specialized appendages for sexual reproduction. Most fairy shrimp reproduce sexually, however a few reproduce by parthenogenesis. The abdomen has 6 segments which do not contain appendages, and a telson, which bears two flattened cercopods.

	The head of fairy shrimp ~~are distinct from the thorax in that the head~~ possesses two compound eyes and two separate pairs of antennae. The shape of the second pair of antennae differ between males and females of the species; the males second pair of antennae are enlarged and specialized (instead of long and cylindrical) in order to be able to better hold females during mating [7].
