Phyllopoda \Phyl*lop"o*da\, n. pl. [NL., fr. Gr. ? a leaf +
   -poda.] (Zo["o]l.)
   An order of Entomostraca including a large number of species,
   most of which live in fresh water. They have flattened or
   leaflike legs, often very numerous, which they use in
   swimming. Called also {Branchiopoda}.

   Note: In some, the body is covered with a bivalve shell
         ({Holostraca}); in others, as Apus, by a shield-shaped
         carapace ({Monostraca}); in others, like Artemia, there
         is no carapace, and the body is regularly segmented.
         Sometimes the group is made to include also the
         Cladocera.

Branchiopoda \Bran"chi*o*poda\, n. pl. [Gr. ? gill + -poda: cf.
   F. branchiopode.] (Zo["o]l.)
   An order of Entomostraca; -- so named from the feet of
   branchiopods having been supposed to perform the function of
   gills. It includes the fresh-water genera {Branchipus},
   {Apus}, and {Limnadia}, and the genus {Artemia} found in salt
   lakes. It is also called {{Phyllopoda}}. See {Phyllopoda},
   {Cladocera}. It is sometimes used in a broader sense.
