Animal Kingdom

• Members of the animal kingdom come in all shapes
  and sizes. However, they all share common, basic
  characteristics.
• w Eat food and move in some way to get food
• w made of millions of cells working together as a
  unit
• w each cell has a cell membrane, but no cell wall

Animal Kingdom

• Think of as many animals as you can. It may seem
  impossible to classify them all! It is really
  quite easy when taken one step at a time.
• All members of the animal kingdom are first
  divided into 2 main groups based on their
  structure - vertebrates and invertebrates.

• Any animal with a backbone is called a
  vertebrate. The backbone of a vertebrate is not
  made of a single bone. It is made of many
  connected bones called vertebrae. All the other
  bones in the body of a vertebrate attach in some
  way to its backbone. This makes the backbone the
  most important bone of the skeleton. Even if a
  vertebrate lacks arms or legs, it always will
  have a backbone.
• All vertebrate animals belong to the Phylum
  Chordata. They are divided into classes based on
  their structure
• and whether they are warm or cold blooded.

5

• Invertebrates are animals that do not have a
  backbone. Invertebrates make up a large part of
  the animal kingdom. Once animals have been
  identified as invertebrates, they can be
  classified further by their structure and form.
  Invertebrate make up 97 of the animal kingdom!
• There are at least 13 invertebrate phyla in the
  animal kingdom. The eight most common are
• - sponges
• - hollow-bodied animals
• - flat worms
• - round worms
• - segmented worms
• - mollusks
• - arthropods
• - echinoderms

• How can you tell if something is an animal?
• eats food, moves in some way to get food, made
  of millions of cells with no cell wall
• All animals can be divided into what 2 groups?
• vertebrates and invertebrates
• How can you tell the difference between the 2
  groups?
• vertebrates have backbones, invertebrates do not
• Are these animals vertebrates or invertebrates?
