Marine Mammals in the Gulf of Maine

humpback whale jumping out of the ocean There are a lot of different species of marine mammals that migrate through or call the Gulf of Maine home, namely whales, dolphins, porpoises and seals! The Gulf of Maine is a special place, with nice cold water, unique underwater mountains and geologic features, and strong currents. This means we have a rich, productive fishery and lots of great food for the whales and seals.

You can learn more about the different cetaceans (whales, dolphins and porpoises) that live here on Blue Ocean Society’s webpage, and then try out our Baleen Whale ID activity to practice your identification skills. If seals are more your thing, first check out our Seal on the Beach Info Sheet to learn more about the SSC Marine Mammal Rescue team and how they respond to stranded seals. You can test your seal expertise with our Marine Mammal Match Seal Activity Sheet.

Have fun and be sure to share your new knowledge and tips for keeping these spectacular marine mammals safe and healthy!
