Kitovi, red Cetacea, dijele se na podred Mysticeti, kitovi usani i Odontoceti, kitovi zubani ovisno o građi usnog aparata. Kitovi usani su pelagične životinje koje se hrane planktonom i ribom. Umjesto zubi imaju usi ili rožnate ploče pričvršćene za rubove gornje čeljusti. Kitovi zubani su karnivorne životinje. U čeljustima sadrže velik broj jednostavnih stožastih zuba za hvatanje i pridržavanje plijena. Kitovi žive u visoko organiziranim jatima, a od svih morskih sisavaca najbolje su prilagođeni životu u moru. Kostur im se razlikuje od kostura kopnenih sisavaca po zakržljalim stražnjim udovima te kostima zdjeličnog pojasa. Uz anatomske prilagodbe, kitovi zubani su razvili različite fiziološke prilagodbe za život u moru. Cilj ovog završnog rada je objasniti anatomiju, fiziološke prilagodbe, biologiju te ugoženost kitova zubana u Jadranskom i svjetskim morima. Whales, order Cetacea, are divided on suborder Mysticeti, baleen whales and Odontoceti, toothed whales depending on structure of their jaws. Baleen whales are pelagic animals and they feed on plankton and fish. Instead of teeth they have baleen or keratin plates attached to edges of their maxilla. Toothed whales are carnivous animals. They have large number od simple, conical teeth in their jaws for capturing and holding their prey. They live in higly organised plot during their whole life and they are most adapted to marine life of all marine mammals. Their skeleton differs from the skeleton of terrestrial mammals by the fact that their rear limbs and pelvic bones are stunted. Besides anatomycal adaptations, toothed whales developed a variety of physiological adaptations for marine life. The goal of this paper is to describe anatomy, physiological adaptations, biology and threats to toothed in Adriatic and world seas.
