Abstract

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.
