Question
Chapter 40, Problem 12TYU
Summary Introduction
To determine: Some benefits and some disadvantages of different skeletal systems that have been evolved in arthropods and vertebrates.
Introduction: Skeletal system forms the framework of the body to protect the internal organ and also helps in locomotion. Different types of skeletal systems have been evolved in arthropods and vertebrates.
Summary Introduction
To explain: The way in which insect skeleton is an adaptation to the insect lifestyle.
Introduction: Insects have the exoskeleton which is made up of nonliving substances such as chitin and forms a layer around the body. The exoskeleton is made up of many plates, which are flexible, long and thick.

4. Using forceps or tweezers, gently pull the 4th or 5th pereiopod to examine its motion. Do so
without tearing the appendage off from the body. How would you describe its maneuverability?
What are the limitations to motion of these walking legs? Given their small size and limited
capacity for muscle attachment, how is it that this animal can use these appendages for motion?
5. Describe the structural differences between the pleopods and the pereiopods up the prawn.
What hypothesis can you make regarding the functional use of pleopods by comparison?
Pleopods of prawns are far larger in comparison to body size then crayfish (see drawings below).
What might this tell you about their use between the two closely related animals?
6. Compare the overall body plan of the prawn to that of an insect like a grasshopper (see drawings
below). Provide a complete side-by-side analysis of the two groups that would include body
regions, and appendages. Focus your comparison on how the…

In your own words:
In which ways does the limb orientation of "advanced" tetrapods differ from that of "primitive" tetrapods? What variations have the manus undergone in the evolution of flight (birds, bats, & pterosaurs), swimming, running, & grasping?
