The term Cetancodonta has been used to group the evolutionary lineage of cetaceans and hippos. The term &#8220;cetacean&#8221; comes from the Greek, &#8220;ketos&#8221; meaning whale or sea monster.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Cetaceans have a single origin, a process known as monophyly. Studies indicate that modern cetaceans evolved from terrestrial animals, which colonized estuarine areas about 55 million years ago. The transition to aquatic life seems to have occurred in the region that today corresponds to the Mediterranean Sea and the Asian subcontinent.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The Cetacea Order includes three Suborders. Archeoceti is made up of extinct species. The Mysticeti Suborder groups the true whales, which, instead of teeth, have baleen plates in their mouth. And the Odontoceti Suborder, which comprises cetaceans with teeth, like dolphins.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The Mysticeti Suborder comprises four families: Balaenopteridae (whales, such as the humpback whale and the minke whale), Balaenidae (whale-whale and bowhead whale), Eschrictiidae (gray whale) and Neobalaenidae (pygmy whale).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The Odontoceti Suborder is divided into 10 families: Ziphiidae (beaked whales), Physeteridae (sperm whale), Kogiidae (Dwarf sperm whales), Platanistidae (Asian river dolphins), Pontoporiidae (La Plata dolphin), Lipotidae (baiji), Iniidae (pink rive dolphin), Phocoenidae (porpoises) and Monodontidae (narwhal and beluga). We consider as dolphins the members of the Delphinidae, Iniidae and Pontoporiidae families.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Dolphins are found in all marine environments in the world, except for the poles. There are species of dolphins that live in rivers, on the coast entering estuaries, in open seas and in some cases they have a wide distribution.<\/span><\/p>\n<p class=\"p1\"><span style=\"font-weight: 400;\">In Brazil, the most easily found dolphins are the pink river-dolphins, la plata, tucuxi, estuarine dolphins, bottlenose dolphins and spinner dolphins.<\/span><\/p>\n<p>[\/vc_column_text][vc_separator][\/vc_column][\/vc_row][vc_row][vc_column][vc_custom_heading text=&#8221;Anatomy&#8221; use_theme_fonts=&#8221;yes&#8221;][vc_single_image image=&#8221;9391&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; onclick=&#8221;link_image&#8221;][vc_column_text]<\/p>\n<div class=\"wpb_text_column wpb_content_element \">\n<div class=\"wpb_wrapper\">\n<p><span style=\"font-weight: 400;\">Dolphins have evolved anatomically to live in the aquatic environment, mainly in terms of external morphology, acquiring a more hydrodynamic shape and becoming the most adapted mammals to water.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Internally, dolphins have an anatomy very similar to that of other mammals, with the same organs and functions.

Species such as the blue whale, fin, sei, and sperm whale have reached threatening population reductions by the middle of the last century. Fortunately, in the 1970s, a global whale protection movement began which culminated in the announcement of a world moratorium on commercial whale hunting (whaling) in the following decade. Intentional capture of dolphins is reduced, but by-catch (unintentionally and unavoidably) and incidental capture (which could have been avoided) is a threat to the conservation of these animals.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Another harmful effect of human action on cetaceans comes from the pollution of the oceans through harmful substances such as pesticides and heavy metals. In Brazil, the contamination of cetaceans by pollution, especially by heavy metals, has already been verified for several species, such as Guiana dolphin and La Plata dolphin. The high amount of litter in the sea, mainly plastic and waste fishing equipment, has been a problem for dolphins. The similarity of appearance between plastics and squid or jellyfish confuses the dolphins, which can lead them to ingest these materials. Remains of fishing gear such as lines and pieces of nets are often observed curled up and slowly cutting off the body of cetaceans.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Seismic prospecting for oil and gas has caused serious problems for cetaceans, as the air guns used in this activity cause explosions that affect the cetacean orientation system, especially the tympanic bullae and the echolocation system.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Although recently tourism activities to watch cetaceans has been also a source of impact on these animals, dolphin and whale watching plays an important educational and developmental role in the non-lethal use of cetaceans but it needs to be carried out under rules of approach to these animals.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p>[\/vc_column_text][vc_separator][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_custom_heading text=&#8221;Origin and Evolution&#8221; use_theme_fonts=&#8221;yes&#8221;][vc_single_image image=&#8221;9389&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; onclick=&#8221;link_image&#8221;][vc_column_text]Dolphins belong to the Mammalia Class, Theria Subclass, Eutheria Infraclass (placental), Cetartiodactyla Suborder, which includes the Arctiodactyla as: cattle, deer, camels, hippos and Cetaceans.
