Abstract

Kitovi i perajari su sisavci prilagođeni na život u vodi. Tijekom evolucije razvili su vrlo raznoliko ponašanje kao prilagodbe na određene probleme s kojima su se susretali. Danas se ponašanje najčešće dijeli na prehrambeno ponašanje, izbjegavanje ili obrana od predatora, seksualno ponašanje, roditeljsko ponašanje, kompeticija i agonističko ponašanje, migracija i orijentacija, te socijalno ponašanje i socijalni odnosi. Pod prehrambeno ponašanje spada pronalazak, odabir i obrada plijena. Uz prehrambeno ponašanje vezana je kompeticija za isti resurs, što je dovelo do evoluiranja efikasnijih metoda lova i u nekih vrsta čak grupnog lova. Kako bi se razvio grupni lov bilo je potrebno razviti složenije socijalne odnose i ponašanja. Socijalni odnosi doveli su do različitih novih tehnika izbjegavanja i obrane od predatora što uključuje veću i raznovrsniju ulogu roditelja u skrbi za mladunce. Evolucijom ponašanja zvuk je dobio značajniju ulogu u životu kitova i perajara. Postao je sredstvo komunikacije, te u nekih vrsta koje koriste eholokaciju sredstvo za pronalazak i lov plijena. Proučavanjem ponašanja i načina komunikacije kitova i perajara imamo priliku zaviriti u um tih životinja, te vidjeti njihovu socijalnu kompleksnost.

Abstract (english)

Cetaceans and pinnipeds are mammals adapted to life in the sea. In the course of evolution they evolved diverse behavior patterns as a response to certain problems they encountered. Today behaviour is divided into: foraging behavior, predator avoidance or defense, sexual behavior, parental behavior, competition and agonistic behavior, migration and orientation, social behavior and social relationships. Foraging behavior includes finding, selecting and processing prey. Foraging behavior is tide with competition for the same resurs, which led to the evolution of more efficient hunting methods, and in some species even group hunting. In order for group hunting to evolve, it was need to evolve more complex social behavior and social relationships. Social relationships led to new evading technics and defense against predators, and that includes more intensive and diverse parental care. In evolution of behavior, sound got a more significant role in life of odontocetes and pinnipeds. It became the means of communication, and in some species that use echolocation, it became a tool for finding and catching prey. Examination of behaviour and communication in cetaceans and pinnipeds provides an opportunity to peek into the minds of these animals, and to see their social complexity.
