Filozoa is a clade (a group of plants or animals with a common ancestor) that is in the Opisthokonta clade. It includes animals, and their close single-celled relatives. These relatives are more closely related to animals than they are to fungi, and other Opisthokonts.

Three groups are in Filozoa: Filasterea, Choanoflagellatea, and Kingdom Animalia. Animalia is the most important one, which has all proper animals in it.
