The Humpback Whale
The humpback whale, whose scientific name is Megaptera novaeangliae - “great wings of New England”, reference to the huge pectoral fins and the region of the United States in which the species was first identified by Science - is one of the best known and most dear among the great whales that inhabit the seas of the planet. Reaching up to XXX in length and weighing around XXX tons, humpbacks are easily identifiable by the almost black coloring of the body, by the typical dorsal fin of the species, by the aforementioned large pectoral fins, which can reach ¼ of the body length and they are generally white, and by the tail whose inferred face has black and white coloring patterns, which are unique for each individual, allowing their individual identification.

Este comportamento é característico da população brasileira de jubartes, e ocorre muito raramente em outras áreas do mundo.
Humpback whales are part of the group of mystics or "fin whales", that is, animals that instead of teeth have a curtain of filter bristles on both sides of the mouth - the "fins", very similar to brushes. This apparatus allows humpbacks to feed on tiny marine plankton organisms, especially here in the Southern Hemisphere of krill, a tiny shrimp extremely abundant in the seas around Antarctica, in addition to facilitating the capture of small schooling fish such as sardines and the like. Opening its huge mouth and expanding its ventral folds, the humpback “bites” a large amount of water, which is then expelled through the fins, which retains the food.
Like all mammals, humpbacks breathe air like us. The “splash” characteristic of whales is not water gushed upwards, but hot air expelled at great speed when the animal exhales, and vaporized water that has accumulated over its breathing hole. Over millions of years of evolution, from terrestrial ancestors, whales and other cetaceans - a group that also includes porpoises and dolphins - have had their nostrils moved to the top of the head, which facilitates their breathing in the aquatic environment. It is estimated that humpbacks can remain up to approximately XXX minutes submerged, but in general here in Brazil they are seen making much shorter breathing intervals.
