In Pacific Rim National Park in British Columbia, Leo has the FishHeads search for the Bay Pipefish, a member of the seahorse family. West is best for this critter, and Christian & Sayat are excited to find all sorts of Pacific creatures as they look for the camouflaging fish. They work with a marine biologist from Parks Canada to sift through the eel grass where the Bay Pipefish live, in the hopes of observing a fish unlike any they've seen yet!
