Thanks to conservation efforts, North Atlantic right whales have made an impressive comeback over the past 70 years, more than quadrupling in population size. CANADA FEEDING GROUNDS UNITED STATES CALVING GROUNDS “There’s a fair amount of speculation involved,” George acknowledges. He explains that the southeast Atlantic waters are shallow and protected, and not as rough as the waters around Cape Hatteras or Cape Canaveral. In addition, the cool water that pools out of the coastal rivers ensures that the ocean remains an ideal temperature for the whales during the wintertime, and the surrounding environment lacks the predatory species that would pose a threat. “All of those things come together to make Georgia a good nursery ground.” The “Right” Whale Averaging between 43 and 52 feet in length and weighing 44 to 77 tons, the large mammals are easily recognizable. Their heads are often dotted with callosities, white with cyamides, or small crustaceans often called whale lice. The corners of their mouths arch above their eyes As part of the baleen whale group, the North American right whale lacks teeth—instead Right whales typically feed in the Gulf of Maine and migrate south to birth their calves. invertebrates, such as krill, by slowly skimming water near the surface of the ocean. The calves that are born off of the Georgia coast typically measure in at 3,000 pounds and about 14 feet long. Most females mature around 9 or 10 years of age, after which they period. They continue to breed every three to six years subsequently. There’s no hard data on their life span, but it’s believed that the whales typically live to be at least 50 years old, and scientists have suggested that some may live to be 100. The right whale received its name from whalers who considered them the “right” whale to hunt because of their slow swimming speed, surface-skimming feeding methods, docile nature, preference for living close to the coast and high blubber content, which means Whale hunters sought them commercially for their meat and whale oil as early as the 11th centu
