The tail of a Humpback whale is seen at the Gerlache Strait, which separates the Palmer Archipelago from the Antarctic Peninsula, in Antarctica on January 19, 2024. A team of scientists have been working since 2014 on the elaboration of a catalog based on the visual analysis of cetacean tails, both in the confines of the continent and in the Colombian Pacific.
