<img src="/ubbthreads/images/graemlins/think.gif" alt="" /> Euh... I think you're wrong on that point. Frogs breath partly (and completely during their "winter sleep") by their skin. I'll check back for sure and tell you. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
Well, that will remain an unanswered life question because I didn't find it. <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />
<img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> But frogs (and close animal classes) are very particular creatures. Here are a few other facts about them:
- Their eyes are made so they can see at 360°
- They become the quite exact opposite of what they were when they transform from tadpoles to adult frogs: tadpoles are herbivorous and exclusively aquatic; they have a long tail, no arms and legs, and breath by branchias adult frogs are excusively carnivorous and live mostly on the ground; they lost their tail and got arms and legs, and lost their branchias for lungs wich allow them to spend some time out of the water, and they breath greatly with their skin.
- frogs and all “amphibiens” (sorry couldn’t find the english word for that) produce a mucus that cover all their body, because their cells are unable to stay hydrated alone. If their skin becomes dry, they dehydrate and it kills them. -Also because of their skin, they are very vulnerable to pollution and microscopic mushrooms, wich poison them at a very small quantity. Frogs are very good indicator of the contamination of water or soil.
- Some big frogs eat other frogs, fishes, rodents and even birds.
- There are about 150 frog species in the world. The biggest one is the Rana Goliath, wich is about 75 cm long and weights up to 4,5 kg; the smallest one is under 9 mm long.
- The main differences between frogs and toads are the skin (flat for the frog, with warts for the toad) and the legs (frog’s are long, toad’s are short; so the frog jumps to move around but the toad only walks). <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
