Aquatic Animals
Animals that live off the Massachusetts coast include the harbor seal, which is seen basking on rocks. The bottle-nosed dolphin often rides the bows of ships. Killer whales, humpback whales, and fin whales also visit the Massachusetts coast. The North Atlantic right whale used to be hunted by Massachusetts whalers. Trout live in the rivers and streams of the state and herring and anchovies live off the coast -- anchovies rarely swim north of Cape Cod. And cod has always been a very important fish for Massachusetts fishing industry.
