phyla
Domains contain these
Phyla is the plural of phylum, a major taxonomic rank in biology grouping organisms that share a basic body plan.
The animal kingdom divides into phyla like Chordata (vertebrates and their relatives) and Arthropoda (insects, spiders, crustaceans).
The Cambrian explosion produced most known animal phyla.
The term sometimes extends metaphorically to broad categories in other domains.
