Mammals
Mammals are warm-blooded vertebrate animals with hair or fur that birth live young. They also have other unique characteristics such as females that produce milk and a brain with a neocortex. Mammals are intelligent and their ability to regulate their body temperature allows them to adapt to any climate.Aardvarks | Anteaters |

Reptiles
Reptiles are cold-blooded animals which lay eggs and have skin covered with hard-plates such as scales. These emerged 310–320 million years ago, much earlier than mammals at about 195 million years ago. A diverse group of reptiles known as the Dinosaurs once dominated every continent on Earth.Alligators | Bearded Dragons |

Insects
Insects are a diverse group of animals that typically have an exoskeleton, three-part body, six legs, compound eyes and a pair of antennae. They are the largest group of animals that constitute more than half of all species. Insects are relatively small due to the limitations of their blind-ended tracheal respiratory system whereby a relatively large insect would require a high oxygen atmosphere.Ants | Aphids |
