FUN FACT!- Many reptiles, contrary to popular belief, evolved before the dinosaurs or developed alongside them!

Turtles/ Testudines

FUN FACT!- In 1968 tortoises were sent up in a soviet space probe to orbit the moon and test conditions for possible lunar missions! Turtle Power!

3Lizards

FUN FACT!- As a defensive mechanism, certain species of lizards can squirt blood up to four feet out of their eyes!

SnakesIncluded in same order as lizards: Squamata.Closely ralated to monitor lizards (e.g. Komodo dragon).Few fossils have been found relating to its origin due to its fragile bones (making ancestors difficult to find).Small vestigial appendages (spurs) are found on primitive snakes.Use smell as a primary sense for probing environments.

Seeing with smell

FUN FACT!- The forked tongue of a snake is used to tell the direction a smell is coming from!

Crocodilians

FUN FACT!- Modern crocodiles can exert ~3700 pound of pressure from their bite.

TuataraLiving fossils closely related to lizards, but an incredibly primitive organism.Survives only by the lack of predators Endemic to unpopulated New Zealand islands.There remains 2 species in their entire orderRats are a natural predator of Tuataras

FUN FACT!- Theres nothing fun about being a tuatara!
