Dominica’s unspoiled marine habitat is home to the largest, toothed whale in the world: the sperm whale. While female and juvenile sperm whales can be sighted throughout the year, the best time to watch for these majestic ocean giants is between November and March—when the male sperm whales migrate.

Dominica is one of the best locales in the world to spot residing or visiting sperm whales, whether visiting during the sperm whale migration or another month of the year. These majestic mammals, with the largest brain in the animal kingdom, have prominent foreheads that make them easy to differentiate from other sea creatures. If you miss spotting them at first, you certainly won’t miss their splash. When breaching, sperm whales jump high out of the water before diving as deep as 3,280 feet back down into the ocean depths in search for food.

Whether whale-watching from your bedroom balcony or venturing via boat with the experts at Fort Young Dive, witnessing whales amid the breathtaking blue of their ocean home is an experience you will recount with your family for years to come.
