Reptiles

I learnt that:

• Reptiles are all lizards
• they are not cold blooded they are exothermic this means that they cant control their own body temperature they must rely on external factors to keep body heat up or down.
• There are three different types of venom. Neurotoxin(nervous system) hemotoxin(hemo means blood) and cytotoxic(the tissue is affected).
• that reptiles are either oviparous(they lay eggs. or ovi-vivi-parous (they lay eggs but internally so the snake is born live.)
