some frogs can blend in with their surroundings. theyre green like leaves, some have brownish tones on their bodies to blend in with dirt and twigs, etc.\n\nalso some tree frogs are poisonous

Survival of the Fittest means that if an animal is stronger or smarter, it will live longer than animals who are weaker or less intelligent. The idea is that animals that live longer will mate and pass on their good genes, while animals that die earlier because of weakness will die before they can pass on their bad genes. So after many generations of this sort of selection (Darwin called it "Natural Selection"), you should have an animal that is stronger, faster, smarter, more brightly colored, better camouflaged, etc.\n\nAn example of this type of selection might be frogs in a pond. Frogs are eaten by large birds like storks or harens. Let's suppose there are two types of frogs in the pond--bright yellow frogs and drab forest green frogs. If you were a stork, which frogs would you see first? Of course the brightly colored ones--they'll be eaten up first while the forest green frogs will blend in better and pass their genes onward to the next generation. By Natural Selection, you should end up with mostly forest green frogs 10 generations down the road.

Their skin. It is permeable to oxygen and carbon dioxide, as well as to water. On land, adult frogs use their lungs to breathe. When a frog is underwater, oxygen is transmitted through the skin directly into the bloodstream. Because the oxygen is dissolved in an aqueous film on the skin and passes from there to the blood, the skin must remain moist at all times.

Believe it or not, Jacks got a good idea, but if that isn't practical for you try this: get some hose and cut it into 3 and 4 foot lengths. Put them out in the field when not in play. They might believe the hose pieces to be snakes and not land there at all. This trick has acutally worked in some places. \n\nThere is an airport where a dog was employed to keep geese away from the end of the runway. It worked.

The spotted frogs have declined sharply. They don't know how to avoid fish and bullfrogs. They didn't evolve in an environment where they had to avoid them.\n\nhttp://www.oregonlive.com/news/oregonian/index.ssf?/news/oregonian/00/07/nw_51spot27.frame

There are many different kinds of animals in the world in order to survive. Each and every animal has their own habitat and according they consume food. Some are herbivorous and some are carnivorous. The food chain goes on to maintain ecological balance .For instance grass is eaten by grasshopper the later is eaten by a frog and the frog is eaten by a snake which is ultimately eaten by a hwak.

the first 1 would be frogs and the 2nd one would be lizards.....simple!!\nP.S.:thanks for the 2 points!

Try hanging a fake owl...it scares them away....

frogs like to swim in the water and are more aquatic than terrestrial, but they have very well developed meaty leg muscles, (both the calf and the thighs) and many muscles the same as humans which they can use for hopping too. They just use their hind legs for hopping though.  Those puny little arms-hands-muscles are not used for much other than propping themselves up when sitting, or a male may squeeze a female when he is on her back mating with her.

cause the frog is too lazy to actually move and get food with its hands. so it uses its slimy toungue

if your keeping one as a pet they'll eat crickets, wax worms, and meal worms, although you dont want to give them wax worms more than twice a week b/c they have a lot of fat in them, and if you give them meal worms you have to crush the heads first b/c the meal worms hard outershell meens its still alive in the frogs stomache and can chew at or through the stomach lining.  i immagen silk worms would also be good if you could get a hold of them

I think what you are referring to is "natural selection" aka "survival of the fittest"\n\nBasically the animal most suited to its environment due to mutation (the ones with genetic proclivity to have longer necks, stronger arms etc) will get more food/mates and will tend to, over a long period, tend to make the species move in that direction.\n\nBasic answer - if you need more drop me a line.

How do you eat a frog?\n\nPut one leg over each ear.

Ideally for the bird it must contain enough energy to justify the energy consumed in gathering it.  If not then the bird was better off staying put.

A frog may breathe by simply opening its mouth and letting air flow into the windpipe. However, it may also breathe with its mouth closed. The floor of the mouth is lowered, causing the frog's throat to "puff out." When the nostrils open, air enters the enlarged mouth. Then, with nostrils closed, the air in the mouth is forced into the lungs by contraction of the floor of the mouth.\n\nSo in order for water to enter their nose, the frog must lower the floor of the mouth (and they know how to prevent this, the same as you know that you must not breath through your nose while under water :P).
