There are about 10 invertabrate phyla containing more than 95% of all animal species.

Invertebrates have a wide range of characteristics, the lack of a backbone being the major common trait.

PowerPoint is a "presentation graphics" program. It is used to visually provide information to a group of people - not just one person sitting in front of a computer. Color combinations and font size must make the slides easily read from a distance.

  1. All living arthropods are placed in one of the three subphyla.link to a local webpage Choose one particular arthropod and make a PowerPoint presentation including the following:
    1. A title slide with a picture of your animal and its common and scientific name (include student name, date, class period and assignment number).
    2. A slide describing the physical characteristics of your animal.
    3. A slide describing the behaviors of your animal.
    4. A slide describing the environment where your animal usually lives.
    5. A slide describing the interactions of your animal with humans.
    6. A final work cited slide (cite correctly).
    7. Include one other picture of your animal on a slide other then the first one.

Animals with a hard exoskeleton must shed the exoskeleton through a process of "molting" before they can grow in size.

 

 

 

 

 

 

 

   

 

While there may be more than one way to describe animal success, insects are the most numerous and diverse animals on earth today.
