The Fall and Rise of the Right Whale

Actually, it’s one of so many good signs that researchers are beginning to hope that for the first time in centuries things are looking up for the right whale. They say the species offers proof that simple conservation steps can have a big impact, even for species driven to the edge of oblivion. North Atlantic right whales, which can grow up to 55 feet long and weigh up to 70 tons, were the “right” whales for 18th- and 19th-century whalers because they are rich in oil and baleen, move slowly, keep close to shore and float when they die. They were long ago hunted to extinction in European waters, and by 1900 perhaps only 100 or so remained in their North American range, from feeding grounds off Maritime Canada and New England to winter calving grounds off the Southeastern coast. Since then, the species’ numbers have crept up, but very slowly. NOAA estimates that there are about 325, though scientists in and out of the agency suspect there may be more, perhaps as many as 400. It has been illegal to hunt the right whale since 1935, when the League of Nations put them under protection. Even so, researchers despaired of ever seeing a healthy right whale population here as long as ship strikes still maimed and killed them and fishing gear strangled them...NY Times
