During our crossing I saw numerous baleen whales belonging to the three species unique to these southernmost seas: the bowhead whale (or "right whale," according to the English), which has no dorsal fin; the humpback whale from the genus Balaenoptera (in other words, "winged whales"), beasts with wrinkled bellies and huge whitish fins that, genus name regardless, do not yet form wings; and the finback whale, yellowish brown, the swiftest of all cetaceans.
Durante la breve travesía, vi numerosas ballenas de las tres especies propias de los mares australes: la ballena franca o right whale de los ingleses, que no tiene aleta dorsal; la hump back, balenóptero de vientre arrugado y de grandes aletas blancuzcas que, pese a su nombre, no forman alas, y, por último, la fin back, de un marrón amarillento, el más vivaz de los cetáceos.
