Frogs come from the amphibian family. This is because they start out as eggs and later turn into tadpoles (with gills) that live in the water. It is not until they grow into frogs that they are able to live out of water. These creatures that live a double life are very interesting subjects that can help children learn about nature.
General Frog Facts
Frogs are cold blooded. This means that a frog's body temperature is the same as its surroundings. The only place that has no frogs of some kind is Antarctica. Frogs like fresh water, especially ponds, lakes and marshes. Frogs are not able to live in salt water, so the sea is not a choice. Frogs absorb water through their skin for hydration. It is a fact that only male frogs croak. There are hundreds of species of frogs; each look different, and not all of them are green.
Frogs start out as eggs in the water. From the jelly-covered eggs — thousands of them — tadpoles emerge. They have gills, a big-head and a long tail. Many of these little guys will get eaten up by fish and other predators. The next step for the tadpole has it turning into a froglet. At this stage it grows four legs and its body shrinks. At the finale stage of growth the froglet becomes a frog. This happens when the tail shrinks away and it grows lungs, which allow it to live outside the water.
What They Eat
Frogs are carnivores, or meat eaters. The preferred meals of most frogs includes moths, flies, dragonflies, mosquitoes and other bugs. Larger-sized frogs have been known to eat small snakes, baby turtles, mice and other smaller frogs and toads. They prefer their dinner alive and will skip over already dead meals.
Frogs have excellent eyesight, which helps them catch their meals. Another thing that helps the frog catch its dinner is that long tongue. Frogs also hear very well. It is the eardrum of the frog that helps identify if it is a male or female. The eardrum is located on the outside of the frog, behind its eye. If the eardrum is smaller than the eye, then the frog is a female. If it is the same size as the eye, it is a male. A frog's powerful back legs are what help it jump so well.
