Animalia is one of the kingdoms in the classification of
living things that has developed.
Animalia has the following general characteristics:
1) Multicellular / metazoa, the body is composed over a
group of cells.
2) Eukaryotic, the cell nucleus has a membrane.
3) Cell bodies do not have cell walls.
4) Heterotrophs, cannot produce own food. 1) Bilateral symmetry, i.e. the body of an individual has
5) No chlorophyll only one symmetry, if it is cut pass through the mouth
6) Aquatic or terrestrial habitat and anus, so that there is equal parts on the left and right
Animalia is divided into 9 phyla in order Features of bilateral symmetry:
based on kinship and level development: 1. The body is divided into dorsal (top/back) and
1. Porifera ventral (bottom/stomach).
2. The body is divided into anterior (top/head) and
2. Coelenterate poterior/caudal (bottom/tail).
3. Platyhelminthes Examples: Platyhelminthes, Nemathel-minthes,
4. Nemathelminthes Annelida, Arthropoda, Mollusca and
5. Annelida Chordata.
6. Arthropods
7. Mollusca
8. Echinoderms
9. Chordata
2) Radial symmetry, that is, the body of an individual
has a lot of symmetry, usually the body arranged in a
circle. Symmetrical animal radial is called radiata.
Characteristics of radial symmetry: the body is only
divided into oral (top) and aboral (lower).
Metazoa Classification Examples: Porifera, Coelenterata, and Echinoderms
belonging to Radiata group
Metazoa are grouped according to body symmetry,
notochord, embryonic layer, and body cavity.
Body symmetry is a term that
describe the symmetry that can be formed
an individual if a line intersects at her body.
