Turtle or tortoise? If you want to get technical, all tortoises are turtles, meaning they belong to the order Testudines. However, not all turtles are tortoises. Tortoises are land animals, and they can’t swim. Though there are land turtles that are not tortoises, like wood turtles and box turtles. Are you confused yet? An easy way to tell the difference is to look at their feet. Tortoise feet look a bit like elephant feet, which is interesting because they’re called “elephantine.” That just means they’re columnar and not webbed like turtles’ back feet are. Turtles’ front feet are like flippers. Tortoises’ are not.
