The Animals of Eaton Canyon

Remember when visiting Eaton Canyon or any other natural area, take your camera or binoculars with you into the canyon, but please LOOK ONLY - touching or even trying to touch the wildlife can stress them and cause illness or death, upsetting the balance of nature.

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.

Invertebrates by Phylum:


Porifera (Sponges)
Cnidaria (Jellyfish, Coral, Sea Anemones, etc.)
Platyhelmintha (Flatworms)
Nematoda (Roundworms)
Mollusca (Snails, Clams, Mussels, Squids, Octopi, etc.)
Annelida (Segmented Worms)
Arthropoda (Insects, Arachnids, Crustaceans, etc.)
Echinoderma (Sea Urchins, Starfish, etc.)

Fish


There are no naturally occurring fish in Eaton Canyon. However, the pond near the Nature Center is stocked with mosquito fish to eliminate mosquitoes from breeding.
