Some researchers believe this behavior may help the whale find food or avoid danger. Their behavior can be unpredictable, and some scientists believe that their intelligence rivals that of humans. As the whales migrate from winter breeding grounds to summer feeding grounds, calves practice hunting and eating solid foods. Since the population of Blue whales is currently at a steady increase, there exists more competition for male mates. The different whale feeding patterns are behavioral adaptations. During periods of rest, whales can often be found logging around (resting motionless) at or near the surface of the water so that they can easily obtain oxygen whenever necessary. Most migrate to warm tropical and subtropical waters in winter months for calving and breeding. In fact, they are so social that they are thought to be the only species of animal that forms societies. It does not store any personal data. Their results were consistent with their hypothesis, providing evidence that right whale mother-calf pairs exhibit acoustic crypsis by reducing the number of higher amplitude calls they produced compared to the juvenile and pregnant whales in the same habitat. They are ready to swim right from the womb and are nursed for about six to seven months as they follow their mother on her marine migrations. Blue whales are an endangered species recognized by the International Union for the Conservation of Nature (IUCN) Red List and the U.S. This Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Over the course of evolution, whales (or rather their ancestors) have evolved and adapted their physiology from living and walking on land to living solely in the ocean. It is weaned at seven to eight months of age at which time it is about 16 m (52 ft) long and weighs 20,900 kg (68,123 lb). WebVocalization and behavior Blue whales live in all the world's oceans, except the Arctic, occasionally swimming in small groups but usually alone or in pairs. Acoustic crypsis is a behavioral adaptation used by animals to reduce detection by eavesdroppers such as predators. Theyve been observed attacking much larger cetaceans such Blue whale flukes spotted in Channel Islands National Marine Sanctuary. The lifespan of these whales is estimated to be 40-80 years of age. This is truly an unforgettable way to experience the 4th of July! There are 55-68 throat grooves, or pleats, along the sides and ventrally that extend from the lower jaw to near or just beyond the navel. Because whales are mammals, they breathe oxygen, and must come to the waters surface to breathe. Its growth is rapid as it gains about 90 kg (198 lb) per day or 3.7 kg (8.2 lb) per hour. Travel - Arctic and Antarctic, Peninsula, With Circle when you use a link on this site to make a purchase on another They constantly need to stay awake. Whales have to adapt to a purely aquatic lifestyle. haemoglobin that stores oxygen in the muscles for use during Animals - A Quick Look. Whales are one of the most social animals on Earth. Using SOSUS researchers were able to make more recordings of whale sounds in one year than had ever been deposited previously in the combined collection of all the worlds cetacean sound libraries. They are interesting creatures and have a lot of behavior that is different from other animals. Whales are some of the most intelligent animals on earth, and they use their intelligence in various ways when it comes to mating and reproductive behavior. The head is uniformly blue, but the back and sides are mottled. Although they are often seen as lazy and sluggish, manatees are very curious and active animals. There are some, however, that may remain year round in colder latitudes depending on ice formation. It was not until 1992 when the array was made available to marine mammal scientists that the snapping shrimp noise was shown to be that of whale vocalizations. Therefore one way these mother-calf pairs can decrease their risk of predation is to decrease their detection using acoustic crypsis.
