Reptiles evolved from amphibians some 300 million years ago. They developed protective, dry, scaly skin, enlarged and more efficient lungs over their predecessors, and tough shelled eggs. These adaptations allowed them to leave the water behind and, for a while, take over the world! Some did decide, however, to return to the water, spending much of their life in or around it.

"The Reptiles: Alligators and Crocodiles" looks at the ultimate predators at the margins of the water and the land. Some amuse us, others terrify us. They slither, swim, walk and crawl, leap and lunge, and some spend their entire lives contained within a shell. Their ranks include some of the most skillful predators on Earth. And their long-departed dinosaur ancestors are an unending source of fascination to humanity, both in fiction and scientific endeavor. They are "The Reptiles," the fascinating subjects of a four-part NATURE miniseries. With guidance from leading experts on "Alligators and Crocodiles," the first episode reveals that the world of these creatures is a lot more complex than we ever imagined. Some of the most surprising sequences reveal that the crocodile is not only the ultimate predator in the natural world but also a highly intelligent animal. The prorgam explores what the future holds for these living dinosaurs. 800 x 600 1024 x 768 Download the Alligators and Crocodiles wallpaper for your desktop!

Home Reptiles : Prairie kingsnake Prairie Kingsnake Lampropeltis calligaster by Jeff LeClere Louisa County, Iowa Van Buren County, IA Louisa Co., IA Captive specimen from Louisa County, IA Photo: Joe Monahan Key to Similar Species Status PROTECTED. It is illegal to kill or collect this species by law in Iowa. These snakes are common in the southern two tiers of counties. We are looking for any reports north of those counties. Description A medium sized Iowa snake that is 30 to 42 inches in length (Conant and Collins, 1991). It is nonvenomous. The prairie kingsnakes general coloration is quite variable. Some specimens can be beautifully light colored, having a light gray or brown ground color and darker body blotches. The blotches are usually brown, but some snakes may have reddish or greenish blotches. Some, especially older specimens, may lose the spots and develop four longitudinal stripes down the back. This appears to be rare in Iowa, however. There are two rather oblong blotches behind the head; and an alternating row (sometimes two) of dark lateral spots on the sides. These lateral spots vary in size, but are never as big as the dorsal blotches. The belly is cream or yellowish with brown checkers scattered randomly about the venter. There is often a dark line from the eye to the angle of the jaw, and there may be dark sutures on the lips. The prairie kingsnakes scales are smooth and the anal plate is single. The prairie kingsnake closely resembles the fox snake. Fox snakes have weakly keeled scales, a divided anal plate, and less markings on the head.

Reptiles What is a Reptile? Reptiles include snakes, lizards, crocodilians, and turtles. Reptiles are cold-blooded. (They depend upon their environment to provide warmth.) Most reptiles are egg-layers, although some produce live young. In cold regions, reptiles hibernate. In extremely hot or dry climates, some reptiles will estivate, or go into a torpor. Because they lack intenal heating mechanisms, reptiles depend on external heat sources. Thus, you will often find them lying in the sun on rocks and logs. Most reptiles have a three-chambered heart.

Reptiles and Amphibians Scientists have catalogued at least 4,780 species of amphibians around the world. The continental United States is home to at least 230 amphibian species. More than 7,800 reptile species have been described world-wide. Reptiles and amphibians are perhaps the most maligned and misunderstood members of the animal kingdom. Often feared and hated by humans, these animals provide critical services within the food chain, keeping insect, small mammal, and even other reptile and amphibian populations in check.

There are fun froggy jokes, a coloring book, and weird frog facts, all of which can supplement a unit on amphibians for younger learners. FrogWeb This Web site, an inter-agency initiative amongst federal, state, and non-profit agencies, and the education and conservation communities, provides comprehensive information about amphibians for both scientists and the general public. Keep abreast of the latest information about amphibian declines and deformities, volunteer your class for various amphibian monitoring activities, and check out the "Educational Resources" and "FrogFun for Kids" areas for a variety of classroom projects and activities. Turtle Trax Although this non-profit organization's site does not contain lesson plans, it does offer teachers plenty of endearing biographies and color photos of specific turtles who have lived in the Honokowai Marine Preserve in Hawai'i, an overview of threats to marine turtles, and actions that everyday citizens can take to help preserve them.

Reptiles of Hiroshima There are 16 species of reptiles in Hiroshima Prefecture. They are 4 species of turtles, 4 lizards and 8 snakes. Most of them are found almost throughout Hiroshima, but geckos and red-eared sliders are small range. Geckos mainly distributed costral parts and islands. The Tawa gecko ( Gekko tawaensis ) inhabits outcrops or rocky mountains and the Japanese gecko ( G. japonicus ) inhabits houses. The red-eared slider ( Trachemys scripta elegans ) is introduced as a pet, and are naturalized in Hiroshima-shi.

Reptiles of the Ancient Seas An Ichthyosaur (bottom) makes a lucky escape from the jaws of an eighty-foot-long Liopleurodon. Perhaps sea serpents don't exist today, but they certainly did in prehistoric times. While dinosaurs ruled the land, their relatives, the great sea reptiles, ruled the ocean. In 1811 the fossilized skeleton of a monster was found embedded in a rock. Scientists were confused by what they saw: the shape of the creature was that of a fish, having a large dorsal fin on the back and flippers. Other features, including a long, pointed jaw filled with teeth, seemed more like a reptile. In the end they decided this strange creature which they named an Ichthyosaur (meaning "fish-reptile") was definitely a reptile despite its shape. The ichthyosaurs were a collection of related species with the same body-shape. One type, Shonisaurus , was almost 50 feet in length. Most of the ichthyosaurs were quite a bit smaller, though, and scientists theorize they may have behaved much like the porpoises of today. Both porpoises (which are mammals) and Ichthyosaurs have a teardrop-shaped torso body, a long snout, short fins up front for steering and a large crescent-shaped tail fin to drive them forward at speeds of up to 30 mph (50kph).
