Humpback whales are creatures of habit. They tend to stick to their normal migration routes and travel with their usual groups. They do this year after year. Recently, a mysterious female whale was confusing scientists with her behavior. The whale strayed thousands of miles in a record-setting journey. Scientists were unsure whether the humpback got lost. They wondered if she was just unusually adventuresome. Scientists may never discover the motivations behind her long trip.Do It!Her behavior was _________.Press enter to interact with the item, and press tab button or down arrow until reaching the Submit button once the item is selectedA peculiarB healthyC nobleD reasonable

The study of cetaceanintelligence has added to our understanding of dolphin behavior. Even thoughcetaceans, which are marine animals including dolphins, whales, and porpoises,are widely considered intelligent species, conclusions about the type andextent of dolphin intelligence have not yet been reached. However, there areseveral things that we do know about the ways in which dolphins communicate andbehave in groups.Researchers study thelevel of communication among dolphins because communication systems can offerinsight into an animal’s intelligence. Dolphins produce two primary types ofvocalizations called clicks and whistles. Dolphins generally use clicks for thepurposes of echolocation and whistles for communication. Dolphins emit clicksas rapid broadband bursts that are sent out into their environment and thenecho back, giving them information about their surroundings. Whistles differfrom clicks by being sent out as narrow-band frequency modulated signals, whichare for communications such as contact calls. Strong evidence supports the ideathat dolphins use signature whistles to identify and call to each other.One hypothesis calledthe “acoustic flashlight” hypothesis maintains that dolphins may be able tolearn passively about their surroundings by listening in on the echolocationinspections of other dolphins. Scientists are researching this idea by lookingat how dolphins participate in postural pointing, an activity that humansperform when they point a finger to direct another person towards an object orlocation.Communication is alsoan important part of how dolphins behave in groups, which can range in sizefrom a pair of dolphins to a pod of hundreds of individuals. Researchers havenoticed that large packs rely on a highly organized method of communicationwhen responding to predators, such as sharks. When a group of dolphins reactsto an unexpected disturbance, it will quickly move in near-unison to avoid thethreat. In this way, dolphins rely on visual and auditory cues to communicatetheir location and to interpret the locations of others in the pod.
