Permeable skin means that substances can pass through the skin barrier. This can also occur through the stratum corneum, hair follicles, and sweat ducts.
Amphibians all have permeable skin that allows them to absorb water, oxygen, and subsequently chemicals all through their epidermis (skin).
With over 50 years of critter experience to my credit and hundreds of zoology teaching hours to people around the world, I have amassed not only a continuing thirst for critter knowledge but a desire to teach others all I can about the majesty and wonder of our natural world. Critter Science is a culmination of such knowledge. I have hands on as well as book acquired intel on all kinds of critters. Whether they're on land, sea, or in the air. I will never say that I know everything about all animals. That's impossible, even for a savant. But, that being said, ask me any animal question and I'll answer it. If I don't know the answer, I'll get an answer for you!
