Branchiopoda (from Ancient Greek βράγχια (bránkhia), meaning "gill", and πούς (poús), meaning "foot") is a class of crustaceans. It comprises fairy shrimp, clam shrimp, Diplostraca (or Cladocera), Notostraca, the Devonian Lepidocaris and possibly the Cambrian Rehbachiella. They are mostly small, freshwater animals that feed on plankton and detritus.
Branchiopoda is a class of small crustaceans with names like fairy shrimp and clam shrimp that live primarily in freshwater environments. These animals are important members of freshwater ecosystems where they feed on plankton and detritus, helping to cycle nutrients through their habitats.

CLASS
鰓足綱(學名:Branchiopoda)是甲壳亚门的一纲,体略呈虾形,是较原始的种类。本物種包括有:天使蝦、介甲目、枝角亞目、背甲目及泥盆紀時期的脂甲目(Lipostraca)鱗蝦科(Lepidocaris)生物。牠們絕大多數的體形都很小,以以浮游生物和碎屑為食。除了枝角亞目物種是在海洋生活以外,其他物種都是在淡水生活。

Branchiopoda (from Ancient Greek βράγχια (bránkhia), meaning "gill", and πούς (poús), meaning "foot") is a class of crustaceans.

They are mostly small, freshwater animals that feed on plankton and detritus.
==Description== Members of the Branchiopoda are unified by the presence of gills on many of the animals' appendages, including some of the mouthparts. This is also responsible for the name of the group (from the , gills, akin to , windpipe; , foot). They generally possess compound eyes and a carapace, which may be a shell of two valves enclosing the trunk (as in most Cladocera), broad and shallow (as in the Notostraca), or entirely absent (as in the Anostraca). In the groups where the carapace prevents the use of the trunk limbs for swimming (Cladocera and clam shrimp), the antennae are used for locomotion, as they are in the nauplius. Male fairy shrimp have an enlarged pair of antennae with which they grasp the female during mating, while in the bottom-feeding Notostraca, the antennae are reduced to vestiges. The trunk limbs are beaten in a metachronal rhythm, causing a flow of water along the midline of the animal, from which it derives oxygen, food and, in the case of the Anostraca and Notostraca, movement.
