Animal behavior is the scientific study of the observable actions, interactions, and behavioral patterns of animals, typically investigated within ethology, behavioral ecology, and comparative psychology. It encompasses mechanisms (proximate causes such as neural, hormonal, and genetic control), development (ontogeny and learning), function (adaptive value in survival and reproductive success), and evolution (phylogenetic history and divergence among taxa). Research on animal behavior quantifies activities such as foraging, mating systems, parental care, communication, social organization, and antipredator strategies, often integrating experimental, observational, and modeling approaches to understand how behavior emerges from organism–environment interactions and contributes to fitness and ecological dynamics.
For dolphins, the ocean is a world of sound. Their whistles carry social information, helping them communicate and stay connected, while echolocation—rapid-fire clicks—functions like underwater sonar, helping them navigate ...

Mice use almost completely distinct sets of neurons for their two different types of vocalizations—the squeaks they produce when in distress or fighting and the whistle-like ultrasonic vocalizations they use when communicating ...

Being an elite athlete—at least for a mouse—does not shorten lifespan or limit how many children one can have. This is the finding of a study 30 years in the making, and it runs counter to accepted evolutionary theory.
