Amidst the dense cedars and Sitka spruces of Canada's Great Bear Rainforest, the Vancouver Coastal Sea wolf roams free. These canines, seen in British Columbia in today's image, thrive in this ecosystem, which stretches from the north of Vancouver Island to the Alaskan border. This unique subspecies of the grey wolf is specific to the region and leads a semi-aquatic lifestyle, swimming between islands in search of food. Their diet primarily consists of fish, clams, mussels, crabs, otters and seals. This marine-based diet is a major difference with other wolf species, which feed almost exclusively on meat. These animals live in closely bonded groups, communicating with each other through growls, barks and whines, so they're often heard before they are seen.
