We have divided our local wildlife into six major categories. The first is the invertebrates, whose numbers far exceed all the others combined. The last five – fish, amphibians, reptiles, birds, and mammals – are vertebrates and are listed in the order in which it is believed that they evolved. Just click on a name to find photos and information about the animals in that group.

Mollusca (Snails, Clams, Mussels, Squids, Octopi, etc.)
