An At-A-Glance Guide to Marine Life
|
Explore the seashore and some of its fascinating marine life.
Clicking on the thumbnails will open up a pop-up window with a larger image, so be sure your pop-up stopped is turned off.

For her expert help in identifiying much of the sea life on this page, we give many thanks to Moretta Frederick, Collections Manager of Invertebrates, Fish, Amphibians and Reptiles at the Royal BC Museum in Victoria.
