The Wolves That Swim Like Otters and Eat Like Whales
When you picture a wolf, you probably imagine a predator chasing deer through a snowy forest or across a mountain range. But along the rugged, misty coastline of British Columbia, Canada, there lives a unique population of wolves that has completely rewritten the rulebook on lupine behavior. They are known as the Sea Wolves.
These are not your average gray wolves. Genetically distinct from their inland cousins, Sea Wolves (a variety of Coastal Wolf) have evolved to survive entirely off the ocean. They are master swimmers, capable of swimming up to 7.5 miles (12 km) between islands in the freezing waters of the Pacific Northwest. Their paws are slightly webbed, and their bodies are smaller and sleeker than inland wolves, helping them navigate the water and the rocky shorelines.
What is most fascinating is their diet. Up to 90% of their food comes from the sea. They hunt seals, river otters, and feast on barnacles and clams, which they dig out of the sand. During the salmon spawning season, they become expert fishermen. Interestingly, researchers have observed that Sea Wolves often eat only the heads of the salmon. Why? Because the head contains the most nutritious fat, and the body of the salmon can carry parasites that are harmful to canids. It is a brilliant, learned survival strategy passed down through generations.
These wolves live in the Great Bear Rainforest, one of the last pristine wildernesses on Earth. Their existence is a powerful example of evolution in action—showing how a species can adapt its physical form and behavior to thrive in a totally unexpected niche. They blur the line between land and sea, living as ghosts in the coastal mist.
