露脊鯨
Like other right whales, they are rather active on the water surface and curious towards human vessels. Southern rights appear to be more active and tend to interact with humans more than the other two northern species. One behavior unique to the southern right whale, known as "tail sailing", is that of using their elevated flukes to catch the wind, remaining in the same position for a considerable amount of time. It appears to be a form of play and is most commonly seen off the coast of Argentina and South Africa. Some other species such as humpback whales are also known to display. Right whales are often seen interacting with other cetaceans, especially humpback whales and dolphins. There have been records of southern rights and humpbacks thought to be involved in mating activities off Mozambique, and along Bahia, Brazil.
