Amphibians need wet skin at all times to breathe through the pores on their skin .
I believe frogs have wet skin because its mucus; it's needed to absorb nutrients, and it also provides oxygen for the frog.
Amphibians breath also through their wet skin , this is called cutaneous respiration . It takes place by diffusion.

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!
Because your skin is waterproof.
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.
toads soak in water from its skin
The chemicals in the disinfectants could soak through your skin and into your blood stream causing a number of different serious symptoms. I'd stick with soap and water.
