Sea lions walk on land using their long front flippers and earflaps, which seals lack. However, seals glide through water by pushing with their strong front flippers, which sea lions also have. Sea lions are generally larger than seals, which is why male Steller sea lions, found in British Columbia, can grow over 9.84 feet (3 m) long and weigh over 1102 lbs (500 kg), while California sea lions reach a maximum weight of 661,4 lbs (300 kg). The most common seal in British Columbia is the harbor seal. Show more
