The Ledge itself lies about 15 miles offshore and is about 30 miles long, extending from Cape Ann, MA northward to the middle of Maine. Back to Top 5. Our whale watch is highly educationally oriented, giving passengers the opportunity to participate in data collection and other hands-on activities. These are some good questions recently asked aboard our whale watches. We can travel anywhere from 6-25 miles offshore to find whales.
Dolphins use echolocation to find their food.
Baleen whales, on the other hand, do not have that same organ in their head that dolphins do, so we think they find their prey mostly by hearing. Hearing is the whale's strongest sense - a baleen whale probably hears schools of fish moving through the water, and when they get close enough, it can follow the fish with its eyes. Generally, it's easier to spot whales in calm water, because there is often good visibility, and it is easier to pick out a whale's back when it surfaces if there aren't any ocean swells around it. Common theory has it that the ocean started with water vapor that came from molten rock early in the history of the Earth. This vapor formed into massive clouds around the Earth, and as the Earth's surface temperature fell, it began to rain.
