Also note special features of molar teeth in the bobcat and the mule deer. If it’s easier to instead do this on the field guide with an annotated picture of each skull type, that works too – just note that here.Page < 3 of 7 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.
