Turtles are reptiles that spend their days both on and off land. They are cold blooded animals that are easily recognizable by their hard exterior shell they use for both protection as well as their home.
Depending on the breed of turtles, some of them can invert their head and their legs to hide inside their shell as a way to fend off predators. Turtles vary in size and life span. Some breeds of turtles are known to live over 100 years while reaching weights in excess of a couple hundred pounds.
Many mistake turtles as amphibians, but they are actually reptiles.
