Phyllopoda \Phyl*lop"o*da\ (f[i^]l*l[o^]p"[-o]*d[.a]), prop. n.
pl. [NL., fr. Gr. fy`llon a leaf + -poda.] (Zool.)
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}}.
[1913 Webster]
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.
