Frogs are incredible marvels of nature
They are moist-skinned animals with no tail, no neck, long back legs, and bulging eyes. They do not have hair, feathers or scales. They begin life as a water animal and later change shape and go out to live on land. Recently, scientists have discovered that some of them can even switch their gender. Yes, frogs (and toads) are true marvels of nature! There are nearly 4,000 species of frogs worldwide and every year more species are discovered. They can be found on every continent except Antarctica. Fossilized remains of the earliest frogs date back 150 million years to the Jurassic period. A frog found preserved in amber in the Dominican Republic is believed to be 30 to 40 million years old. Frogs have been around for a long time and if humans don’t manage to wipe them out with pollutants and pesticides, they should still be around for a lot longer. The skin of frogs is quite amazing, because it serves many purposes – as a temperature regulator, a respirator, and organ for water absorption, and the site of glands that secret mucous and poison. Their skin will often change colors with changes in temperature – turning light on hot days to reflect the sun’s rays and turning dark on cold days to absorb the rays. Their skin is permeable so they can absorb the water they need to survive through their skin rather than by drinking it. They also use their skin (as well as lungs) to breath. Mucous glands help to keep it moist and slick which aids in both breathing and escaping predators. Frogs are carnivores, eating mainly insects, earthworms, minnows and spiders. Most use their sticky tongues to capture prey which they swallow whole. To aid in the swallowing process, the frog’s eyes sink through openings in the skull and force the food down the throat. The Bullfrogs is the largest frog in Illinois and consequently, can eat much larger prey. In fact, it eats almost anything it can at least partially swallow—birds, snakes, fish and even bats. In northwest Illinois we have 10 species of frogs and toads: American toad, bullfrog, cricket frog, green frog, grey tree frog, northern leopard frog, pickerel frog, spring peeper, western chorus frog and wood frog. The Illinois Department of Natural Resources has a great website where you can go to see photos and hear the sounds of Illinois frogs: www.dnr.state.il.us/education/CLASSRM/aquatic/frogs_toads.htm.Northern Leopard Frog - News
