The Bottlenose Dolphin, a large dolphin with an elongated snout that resembles a bottle, is St. Maarten’s most common dolphin species. A 2011 census found that the Bottlenose Dolphin is the second most common marine mammal after the Humpback Whale (Megaptera novaeangliae). Nineteen individuals were recorded, many within the newly established Man of War Shoal Marine Park. Females with calves are typically spotted between February and May. Females give birth to a single calf, every two to three years. The calf is nursed for up to 18 months, and stay with their mother until they are about 5 years old. This dolphin always looks like it is smiling because of the way it’s mouth line curves upwards.
