Known as the Right Whale because it was the whale the whalers wanted most, this baleen whale (plankton-sieving, as opposed to toothed whales like the Sperm Whale) has been in hard times since the whaling era nearly wiped them out. Now it seems that their numbers are most influenced by collisions with shipping, and nothing can or will be done about that.
There are two populations of this mighty 50-foot creature, one in the southern hemisphere and one in the northern. The North Atlantic species is the one that is in trouble. I saw a mom and calf in the Gulf of Maine ten years ago - a special sight. Our New England Humpbacks seem to be doing OK, but the Rights are on a steep decline which only luck or nature can reverse.
