Phylum
In biology, a
phylum
(;
plural
:
phyla
) is a
taxonomic rank
below
kingdom
and above
class
. Traditionally, in
botany
the term
division
was used instead of "phylum", although from 1993 the
International Code of Nomenclature for algae, fungi, and plants
accepted the designation "phylum". The kingdom
Animalia
contains approximately 35 phyla,
Plantae
contains 12, and
Fungi
contains 7. Current research in
phylogenetics
is uncovering the relationships between phyla, which are contained in larger
clades
, like
Ecdysozoa
and
Embryophyta
.
