These whales spend their summers in the cooler waters of the Arctic or Antarctic oceans, and their winters in the tropical waters near the equator. By using echolocation toothed whales can determine many factors about their environment, such as how far an object is, how fast it is moving, whether it is above or below them, what direction it is traveling in, how large it is, and whether it is a hollow or solid object. Wombats are nocturnal animals and spend most of their time eating, sleeping, and grooming. Their food of choice are krill small, shrimp-like crustaceans that swim in massive swarms though their gulping feeding strategy doesnt allow them to be picky. Their bodies are long and slender, and each whale has a unique marbling pattern of their skin, which scientists and observers can use to tell whales apart. Like other whale and dolphin species, blue whales communicate with vocals and nonverbal body language. Through the years the Navy observers ignored the natural sounds of the ocean as they listened intently for the man-made noises of submarines. Whales have a highly developed sense of smell that helps them find food and navigate through the ocean. When fully grown, blue whales can reach lengths of 70 to nearly 90 feet and weigh as much as 300,000 pounds.

Neither actual mating of blue whales nor birth of a calf have been observed in modern times, and the breeding grounds for some populations are still unknown. Due to this fact, whales are never able to fall completely asleep because if they did, there is a good chance they would drown. Most blue whales migrate from their colder water feeding grounds to warmer water latitudes to mate and calve. 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. One of the most important senses a whale has is its sense of hearing. Like other whale and dolphin species, blue whales communicate with vocals and nonverbal body language.

Their baleen consists of 260 to 400 black, coarse, broad, overlapping plates hanging from each side of the upper jaw. What is the population density in various parts of the world ocean? This Arctic creature has a long, tusk-like proboscis which is actually a tooth that grows continuously and can reach lengths of over 6 feet!

Blue Whales are the largest animal inhabiting the earth, spanning as long as three school buses. | Echolocation is when mammals produce sound waves and listen to the echoes that return from objects around them. 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. Some of the reasons why whales are at risk include human activity such as hunting, pollution, and climate change. First, it is important to learn about their habits and how they interact with their environment. Southern blue whales are about 3.5 m (11 ft) larger than northern, a difference believed to be the result of the more abundant supply of krill in the Antarctic Ocean. Whale populations are sensitive to environmental changes, so they often change their behavior in response to fluctuations in their environment. Most migrate to warm tropical and subtropical waters in winter months for calving and breeding. (Krill preferences are determined by analyzing fecal samples.)

There are three main types of whale behavior: social, solitary, and aggressive. Once a whale has chosen a mate, it may commence mating by performing whats called a breaststroke..

Unlike smaller species, these whales have a much lower risk of being attacked by a predator and thus do not need to rely on large pods or groups for protection. The red coloration a result of its krill diet. Whales Recent acoustical studies indicate that males may vocalize to attract females by using a very low frequency call referred to as the A call.
