Kingdom Animalia

Finally…our own kingdom!

What is an animal?

A multicellular organism that depends on other living

things for food, can move from place to place and can

reproduce sexually or asexually.

They have 6 main characteristics…

1. Animals are multicellular

2. Animal cells are eukaryotic

3. Animals depend on other living things for food

4. Animals digest their food

5. Most animals move from place to place

6. Animals reproduce sexually, asexually or both

Different food…different animals

Herbivore: eat only plants

Carnivore: eat only animals

Omnivore: eat both plants and animals

2 Different Groups of Animals

Vertebrates: an animal with a backbone

Invertebrate: an animal without a backbone

Animals with Different Shapes

Animals come in different shapes and symmetries

Symmetry: how the body parts of an animal are arranged

Radial Symmetry: animals with body parts that are arranged around a center point (round)

Bilateral Symmetry: animals that can be divided into 2 identical halves

Try it! Which symmetry?

9 Different Phyla

There are LOTS of different animals and they all belong in a different

phylum with others that are similar to them!

Phylum Porifera

Aquatic organisms, no tissues or organs –sponges

Phylum Cnidaria

Digestive cavity, most with tentacles that sting, aquatic –jellyfish, corals, hydra, sea anemones

Phylum Platyhelminthes

Flattened bodies parasitic and free-living - flatworms

Phylum Nematoda

Round body, free-living and parasitic forms -roundworms

Phylum Mollusca

Hard shell, soft foot to move – clams, snails, squid, octopus

Phylum Annelida

Segmented bodies and round –earthworms, leeches

Phylum Arthropoda

Hard exoskeleton, segmented bodies –insects, crustaceans (crabs), spiders

Phylum Echinodermata

Marine animals, spiny or leathery skin, tube feet –sea stars, sand dollars, sea urchins

Phylum Chordata

Internal skeleton, specialized organs –fish, amphibians, reptiles, birds, mammals
