phylum
Kingdom's major division
Phylum is a major category in biological classification, ranking below kingdom and above class.
It groups organisms that share a fundamental body plan or structural organization.
Animals, for instance, are divided into phyla such as Chordata (vertebrates and their relatives) and Arthropoda (insects, spiders, crustaceans).
The phylum Mollusca includes snails, clams, and octopuses.
The plural is phyla, following the Latin.
