Steller sea lions are year-round residents in the archipelago, often seen in boat harbors and haul-out areas. Sea otters, once hunted to near extinction, can be seen in sheltered waters near kelp beds. Harbor seals are found in protected inner bays and lagoons. The largest marine mammals found in Kodiak waters are fin, minke, humpback, killer and gray whales. Spring and fall are the best times for observing migrating gray whales. Killer whales are common in the spring and summer. Dall and white-sided porpoise are often seen riding a boat's waves, unlike the shy harbor porpoise.
