Turtles will move from one body of water to another throughout the year but most turtles encountered on roadways are females during the nesting season in May and June. Turtles often have to cross roads during these movements.

The origin of chelonians is uncertain, but recognizable turtles are known as far back as the Triassic period, at least 180 million years ago when dinosaurs were becoming the dominant land animals. Although the Triassic turtles did not look very much different from some modern ones, closer examination would have revealed some characteristics absent from turtles living today. For example, some of the earliest known turtles had teeth rather than sharp edged jaws. Much later, towards the end of the Cretaceous period over 65 million years ago, turtles as large as the 3 meter (9 feet 10 inches) Archelon ischyros lived in the shallow sea that covered much of what is now the western United States.

In most turtles, the outer layer of the shell is covered by horny scales called scutes that are part of its outer skin, or epidermis. Scutes are made up of a fibrous protein called keratin that ... makes up the scales of other reptiles. These scutes overlap the seams between the shell bones and add strength to the shell. Some turtles do not have horny scutes. For example, the leatherback sea turtle and the soft-shelled turtles have shells covered with leathery skin instead.

If paid the proper respect the turtles can give you a lifetime memory. There are a couple of subtle signs to watch for when near a sea turtle that signal you may be too close within their comfort zone. "Yawning" type, open mouth movements by the turtle are one. A sign of a more deeply irritated turtle is a "flipper swipe" whereas the turtle swipes his flipper over his forehead area. This is turtle-speak equal to flipping you off! Don't embarrass yourself (or be deemed insensitive) by being flipped off by a turtle, back off if you see that flipper creep up.
