[104], Any historical or current presence of similar groups of residents among the western population is currently unknown, however, whalers' logbooks and scientific observations indicate that possible year-round occurrences in Chinese waters and Yellow and Bohai basins were likely to be summering grounds. North Atlantic populations were extirpated (perhaps by whaling) on the European coast before 500 CE, and on the American coast around the late 17th to early 18th centuries. Their pectoral fins can grow up to 16 feet long! Providing a sensory tool, these hairs feed back information about the whales surroundings.
