Fagatele Bay National Marine Sanctuary on a cloudy day. This bay is an ancient flooded volcano. The water visibility in the bay is normally around 70 feet. The steep slopes surrounding the small bay contain some of Americas's rare paleo-tropical rainforest. Fagatele Bay is a vibrant tropical reef marine ecosystem, filled with all sorts of brightly-colored tropical fish including parrot fish, damselfish and butterfly fish, as well as other sea creatures like lobster, crabs, sharks and octopus. From June to September, Southern humpback whales migrate north from Antarctica to calve and court in Samoan waters.
