Exostles, jointed legs, and segmented bodies are all characteristics of arthropods. gills of amphibians cannot be shared with reptiles because the gills of reptiles cannot be shared. Air enters and leaves the tracheal system through the spiracles. A difference between reptilian eggs and amphibian eggs is that reptilian eggs are usually hard-shelled. Comparing And Contrasting Stories With Similar Characters Teaching { _Zc_wKyc You see, the skin of reptiles and amphibians are uniquely different in BOTH aesthetics and function.
