Daily Question and Agenda

• The BIG Question How do we classify vertebrates
  and invertebrates based on physical
  characteristics?
• March 4 What is an invertebrate?
• Agenda Observing different types of
  invertebrates and outlining notes on
  invertebrates
• Classify Put into groups
• Outline way to show related items of text

Look and Observe

• What is the shape of the body?
• Does the body have any markings on it? Tell me
  about them.
• Does the creature have a mouth? If so where?

I. Invertebrates

• So Many!
• 98 of all indentified species are invertebrates

II. Physical Characteristics

• Hard Bodies
• Exoskeletons
• Hard outer coverings
• Protection
• Clams, mussels
• Arthropods
• Animal with hard outer shell and jointed body and
  limbs
• Largest group of invertebrates
• Insects, crustaceans (lobsters)

14
II. Physical Characteristics

• Soft Bodies
• Earthworms

15
III. Body Plan

• Bilateral Symmetry
• 1. Right and left halves of the body mirror each
  other.
• 2. Animals that move and look for food

16
III. Body Plans

• B. Circular body (Radial Symmetry)
• Arranged around a central mouth- like spokes
  coming out from a wheel.
• Stay in one place

17
IV. Simple to Complex

• Some have developed organ systems while some,
  like the placozoans, survive with few or no
  organs at all.
• 1. Absorb what they need from their environment

18
V. Types of Invertebrates

• Zoologists classify invertebrates into about 30
  major groups.
• Phyla
• Phylum Anthropoda- has the most species (about 1
  million)- insects
• Phylum Mollusca (mollusks)
• Phylum Porifera (sponges)
