Frogs breath primarily through their moist skin, and so their skin is a poor barrier to pollutants in the environment. They also have a two-phase life cycle in which they are aquatic in the egg and tadpole stages and terrestrial as juveniles and adults. This makes them vulnerable to habitat alterations both in the water and on land.

Most frogs and toads breathe (and take in moisture) through their skin through a process called cutaneous gas exchange, but they also have lungs with which they breathe. See similar questions...

First, stand with relaxed but erect posture, chest "comfortably high". Maintain an open stance and attitude, which will allow your body to function freely and without tension. When you take a breath, the lower part of the trunk of the body expands easily, as your ribs expand. Don't "gasp" the air or allow the shoulders and chest to rise. See similar questions...

We like frogs. A lot. We just can't help but love the Red-eyed tree frog, which is so colourful and small. We've chosen him as the Alpha21 mascot because he sticks to things, is stealthy, shows off some gorgeous colours and sometimes eats the competition. Our frog is the Red-eyed tree frog: Found in the tropical rainforests of Central America, the Red Eyed Tree Frog is arboreal and excels at jumping. This species of frog moves in a very stealthy yet deliberate manner. See similar questions...

Reports of malformed amphibians have been reported in 35 states in the U.S. and 3 provinces in Canada since 1996. In Minnesota, nearly three-quarters of our 87 counties have reported malformed frogs since 1996. A map of national reports is available at the North American Reporting Center for Amphibian Malformations. See similar questions...

Most frogs have their camouflage colours "built in" permanently. Colour change in frogs usually have to do with the frogs temperature and perhaps whether it is stressed or not. See similar questions...

Frogs and toads make a variety of sounds, depending on the situation. The most common are "advertisement" calls, and "alarm" calls. Frogs and toads advertise their presence either to ward off challengers to their territories, or to attract mates. Alarm calls serve to startle predators. See similar questions...

Contrary to some opinions, you can breathe during your skydiving experience. Even though you will be falling at up to 120 mph, it is easy to breathe. The wind which enters your lungs does not enter at full speed! It is slowed as it passes through your nose and mouth. Lastly, we skydive up to a maximum height of 15,000ft where there is plenty of oxygen available. See similar questions...

Some people have eliminated their anxiety symptoms simply by changing the way they breathe. A proper breathing technique is very important and requires practice. You breathe now, but the way you breathe may not use your lung capacity. Some people "overbreathe" . . More information . . . Back to Top See similar questions...

Frog populations are disappearing for many reasons. Obvious reasons include pollution in waterways, surface water being drained away, land clearing, and urbanisation. Some less obvious reasons that are affecting frog populations far from human interference may include climate change, exposure to increased UV-B radiation, and emerging diseases.

Until the scientists know the answer there is not a lot that can be done except to continue studying the issue. However, by getting people interested in the issue and by having students involved in writing about it, people will become aware of the issue and about the problems facing frogs and our environment.

Because of the constant pressure of stress in our inner and outer lives, many of us do not breathe naturally. We have become upper chest breathers. This causes us to breathe faster than we should, often bringing about a chronic state of hyperventilation, a state in which we breathe too fast for the real demands of the situation. Those of us who breathe too fast often find ourselves holding our breath in moments of stress and fear. See similar questions...

Yes, when possible. When we breathe through our nose, the hairs that line our nostrils filter out particles of dust and dirt that can be injurious to our lungs. If too many particles accumulate on the membranes of the nose, we automatically secret mucus to trap them or sneeze to expel them. The mucous membranes of our septum, which divides the nose into two cavities, further prepare the air for our lungs by warming and humidifying it. See similar questions...

In the air-breathing pulmonates the interior of the mantle cavity is converted into a lung and a pumping mechanism for renewal of air is established. The restriction of the respiratory aperture is necessary. The mantle forms the roof of the cavity and is covered with ridges in which pulmonary veins converging towards the auricle. The floor of the cavity is arched and has a layer of muscles, which contract rhythmically. See similar questions...
