KINGDOM ANIMALIA CHARACTERISTICS BODY CHARACTERISTICS HOW THEY ARE GROUPED PHYLA

GENERAL 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

HOW ANIMALS ARE CLASSIFIED: 1- BODY STRUCTURE 2- DNA C- HOW IT DEVELOPS

WHAT COMMON CHARACTERISTICS DO ALL THESE CREATURES SHARE SINCE THEY ARE ALL ANIMALS?! The Aye-Aye is a nocturnal animal that lives in Madagascar. The angler fish The Kiwi bird, although only the size of a chicken lays an egg that weighs about 1 pound!.

All animals, no matter their size, appearance or habitat they live in carry out the SAME functions. Get food and oxygen Keep internal conditions stable Move Reproduce

Animals Move?! How about an oyster? Coral? Barnacle? Glass Lizard? How do things move?

Animals Reproduce! Sexual reproduction: the fertilization of an egg by sperm ◦ (2 sex cells join) Asexual reproduction: a new organism reproduces another organism similar to itself ◦ (one parent)

Classification of Animals The animal kingdom 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 ANIMALS 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 SYMMETRY BILATERAL - THE BODY CAN BE DIVIDED INTO TWO IDENTICAL HALVES BY ONLY ONE SPECIFIC PLANE THROUGH THE LONGITUDINAL AXIS.

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

BODY SYMMETRY ASYMMETRICAL - THE BODY HAS NO DEFINITE SHAPE AND CANNOT BE DIVIDED INTO TWO IDENTICAL HALVES. Sea sponge is asymmetrical

DIRECTIONS ON AN ANIMAL BODY DORSAL - TOP SURFACE ANTERIOR - FRONT END VENTRAL - BOTTOM SURFACE POSTERIOR - HIND END

Developmental Stages 1.ZYGOTE-THE FERTILIZED EGG. 2. EMBRYO-THE DEVELOPING FERTILIZED EGG. 3. FETUS-THE EMBRYO HAS DEVELOPED TO THE POINT THAT IT BEGINS TO RESEMBLE THE MATURE ORGANISM.

9 Phyla of the Animal kingdom 1)Porifera6) Mollusca 2)Coelenterata 7) Echinoderm 3)Flatworms8) Arthropoda 4)Roundworms9) Chordata 5)Segmented worms

Porifera  Means “having pores”  asymmetrical  Ex: sponges

Coelenterata  Sac-like body  Have tentacles  Ex: hydras, jelly fish, coral,  sea anemones  Radial symmetry

3 Phyla of Worms:  Flatworms  Roundworms  Segmented worms

Molluska:  Hard shell surrounding soft body parts  Live in water & damp places  Examples:  Snail, & Sea Scallop  Only a few do not have shells:  Octopus & Sea slug

Echinoderms:  Means “spiny-skin”  Star shaped  Radial symmetry  Spiny Ex: Starfish & Sea Urchin

Arthropoda:  Makes up 75% of the animal kingdom  Basic Characteristics:  hard external skeleton  segmented body  jointed legs  Ex: beetle, milli & centipede, spider, crab

Chordata:  Vertebrates  Have internal skeleton  Vertebral column  Limbs  CLASSES: fish, amphibians, reptiles, birds, mammals
