BOSTON - About 75 North Atlantic right whales, representing about 20% of the critically endangered species' population worldwide, have gathered in an area off the coast of New England.

A group of scientists saw over 75 North Atlantic right whales gathered in the Gulf of Maine. Here's what we know.
