GENERAL CHARACTERISTICSGENERAL CHARACTERISTICS

Most complex of all kingdoms

Multicellular (made of many cells)

They obtain food from OUTSIDE SOURCES

They move from place to place to get food (at least at one point in their lives)

Heterotrophs/consumers who eat other things for energy

Cell membrane- no cell wall

is divided in to phyla.All vertebrates are

divided into one phylum (CHORDATA), while all the other invertebrates make up the remaining animal phyla.

BASIC BODY CHARACTERISTICS OF BASIC BODY CHARACTERISTICS OF ANIMALSANIMALS

Body symmetry - the way body parts are arranged around a point or central axis. Directions on the body - used to describe areas on the body of an animal. Pattern of body development - a sequence of developmental steps.

BODY SYMMETRYBODY SYMMETRY BILATERAL - THE BODY CAN BE DIVIDED

INTO TWO IDENTICAL HALVES BY ONLY ONE SPECIFIC PLANE THROUGH THE LONGITUDINAL AXIS.

BODY SYMMETRYBODY SYMMETRY RADIAL -

THE BODY CAN BE DIVIDED INTO TWO IDENTICAL HALVES BY ANY PLANE THAT PASSES THROUGH THE LONGITUDINAL AXIS.

BODY SYMMETRYBODY SYMMETRY ASYMMETRICAL -

THE BODY HAS NO DEFINITE SHAPE AND CANNOT BE DIVIDED INTO TWO IDENTICAL HALVES.

Sea sponge is asymmetrical
