Biology ntawm cetaceans yog ib qho ntawm cov kev tshawb fawb tseem ceeb tshaj plaws vim tias qhov kev hloov pauv huab cua thiab cov ntses ntses ntses yuav tsum tau ua kom tswj tau lub neej hauv dej. Cov ntaub ntawv fossil ntawm cetaceans yog nplua nuj, thiab txawm hais tias muaj ntau qhov kev saib xyuas rau lub hauv paus chiv keeb ntawm whales los ntawm cov av artiodactyls, nws yog ib qho tseem ceeb kom paub tias biology, physiology, thiab tus cwj pwm ntawm niaj hnub cetaceans tsis tau nyob twj ywm unchanged txij li thaum no pib hloov mus ua. dej. Cov phau ntawv no tham txog thiab nthuav tawm cov ntaub ntawv tshiab ntawm tus cwj pwm thiab biology ntawm whales thiab ntses taub ntswg ntev xws li: lub cenozoic ib puag ncig kev hloov pauv thiab evolution ntawm baleen whales, ecological thiab evolutionary divergence nyob rau hauv whales thiab dolphins, parasite fauna ntawm cetaceans, thiab lwm yam (los ntawm Amazon) .
