Vertebrates 3

This DVD offers a clearly structured overview over reptiles with an emphasis on the following aspects: The origin of reptiles is proven by fossil finds from all over the world. The skeletons are proof that reptiles were not confined to life on land but were also adapted to water and the air. The typical common characteristics of reptiles, such as the coat of scales and a poikilothermic body temperature, as well as the extremely different appearances of poisonous snakes and constrictors, turtles, lizards and crocodiles are discussed in detail. The different methods of finding food both as a herbivore or as an ambush predator with the use of poison or with the help of a pit organ are shown. The “invention” of the amnion made the reptiles’ reproduction independent from water and enab- led them to lay their eggs on land.
