Vertebrate Adaptions For Terrestrial Life

... the water. All animals need to respire, but I have no idea why. Maybe you would like to answer that?

... . . . living out a flawed paradigm? Canada is a prime example of a country that is continually weighing its power and influence on the natural and manmade worlds.
