Amphibians need wet skin at all times to breathe through the pores on their skin .
to live
Yes they do, especially the skin at the underside of the thighs is very well adapted to soak up water. In fact you might say a frog drinks with it butt!
Water may not soak into your skin immediately due to the presence of a thin layer of oil on the surface of your skin, which acts as a barrier to water penetration. Additionally, the outermost layer of skin, called the stratum corneum, is designed to be water-resistant to prevent excessive water loss from the body. If you stay in water for a prolonged period of time, then the water may eventually penetrate through the skin.
Amphibians normally have smooth, oily skin. So if you were to pet a lizard, you may notice it's skin isn't exactly wet, like it may sound. That oilly part is formed by water. For exsample; Frogs soak the water in to their skin as they swim. This water drys alittle bit, and then keeps their skin oilly. If a frog doesn't live near any water, it's skin may dry out. Sadly the frog would die. I hope this helped you.

Do not attempt to tear or force apart the glue. This could rip your skin. Apply acetone-based nail-polish remover to the area. The acetone breaks down the bond. If there's a lot of glue on your skin, soak the skin in nail-polish remover to dissolve the bond. Clean the area with soap and water after removing the glue. If you don't have nail-polish remover, soak the affected skin in warm, soapy water. Slowly roll the skin to work the bond apart as the warm water soaks through. Continue doing this until the skin is free of glue. Relative links http://bit.ly/5evRe3
