Summary: Amphibians, frogs and some salamanders, breathe through their skin. Did you know their skin is permeable, or thin enough for gases to pass through! ?
The movement of different materials through a cell membrane is called osmosis or diffusion. This is possible because nutritive molecules are smaller than the cell membrane pores. If a molecule is too large, it will not be able to pass through.
In this lab, we will represent a cell membrane of our amphibians. Different materials will be tested to see which are small enough to pass through the permeable membrane and which are too large.

The Herpetology Lab matches up with our museum tour all about our animals on exhibit.
Reptiles and amphibians have sense organs that are highly specialized depending upon the species. These specializations in sight, smell, taste, hearing and/or touch increase the species chances of survival whether it be to evade a predator, catch their next meal or locate a mate.
