Viviparous: To be born alive inside the womb of the offspring's mother. Most mammals (the platypus is ovoviviparous), some reptiles (the skink which are types of lizards), and a few fish (such as the bull shark).

Ovoviviparous: Uses internal fertilization just like Viviparous animals, but instead of a live birth, the offspring is in an egg. Platypuses and four species of echnida, which are also known as spiny anteaters, are ovoviviparous (They are the only mammals that are ovoviviparous!), most reptiles, and most fish.

Ectothermic: Another meaning for cold-blooded. Animals that are ectothermic have to rely on external sources to regulate their body temperature. An example of an ectothermic animal is snakes.

Endothermic: The opposite of Ectothermic. Endothermic is another meaning for warm-blooded. Endothermic animals can regulate their body temperatures. An example of an endothermic animal is humans.
