Fossorial III. Arboreal LocomotionIV. Aquatic Locomotion V. Aerial LocomotionCurrent LectureI. Terrestrial Locomotion- Typeso Cursorial- running locomotion Having adaptations for runningo Ambulatory- walking locomotion Unspecialized o Graviportal- adaptations for supporting heavy body weight Ex. Elephants Digits are spread apart o Saltatorial- jumping or hopping II. Fossorial- Having adaptations for burrowing o Enlarged forelimbsThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.o Reduced eyes and ears o Enlarged pectoral musculature III. Arboreal Locomotion- Adaptations for movement through treeso Elongated appendages o Long tail prehensile o Generalized limbs joints- provide a very wide range of movement o Increase in size and function of the eyes (depth perception)- Specializationso Brachiation- swinging underneath branches o Scansorial- climbing on the surface of trees using claws IV. Aquatic Locomotion - Amphibious: like otters, beavers, muskrats, ect.o Waterproof, insulated fur, flattened tail, webbing between the toes - Aquatic: seals, sea lions, walrus, ect.o Appendages modified into flippers o Insulate fur; thick layer of fat - Marine: cetaceans o Fusiform body shape, loss of hind limbs, tail modified into a horizontal fluke, no fur blubber V. Aerial Locomotion - Volant: “to fly”o True Flight- only in Chiroptera (bats) Forelimbs are wings o Gliding- several rodents Patagiums on the
