Whales are huge, but elusive and difficult Among these adaptations are: streamlined bodies for efficient movement through water; forelimbs modified into flippers to aid in steering; hind limbs internalized remnants reducing drag; tail positioned horizontally to achieve a powerful up and down propulsion; hair replaced with under-skin blubber to provide warmth and buoyancy; structure of nostrils changed to blowholes that can be sealed off under water and position shifted to top of head to give ability to breath air before the rest of the body surfaces and while swimming at the surface without lifting the head; highly developed hearing that relies on an internal system of air sinuses and bones to detect sound instead of external ears; lung capacity that enables them to exchange 80-90% of lung air volume(humans can exchange only 17-20%) ; reproductive organs internalized to prevent drag when swimming; and countercurrent heat exchangers in the tongue that enable the whales to take in gallons of very cold water during feeding and still not become hypothermic. It is these mottling patterns, their unique fingerprints, which have formed the basis for photo identification of individual blue whales just as saddle and eye patches of killer whales and the black and white pigmentation of the underside of humpback flukes are used.

Travel | Whales use a variety of signals to communicate with each other, including vocalizing, tail slapping, and head nodding. The lifespan of these whales is estimated to be 40-80 years of age. As the whales migrate from winter breeding grounds to summer feeding grounds, calves practice hunting and eating solid foods. Because whales are mammals, they breathe oxygen, and must come to the waters surface to breathe. Research has indicated that these whales may depend on low frequency and high decibel sounds to communicate, find krill swarms, reproduce, and possible navigate. Other adaptations are behavioral, that is, things organisms do. In conclusion, whale behavior is an interesting and complex topic. Despite their massive size, blue whale migrations are hard to keep track of, so we dont yet know much about specific migratory routes.

Some of the more common behaviors observed in belugas include tail-slapping, breaching, spyhopping, and bubble blowing. Krill is a small, shrimp-like crustacean, and the blue whale can eat up to four tons of krill per day. When submerged underwater, their diving reflex allows them to distribute oxygen and blood to vital organs while restricting it in other non-essential areas. over a year and feed on milk produced by the mother. The frequency is as low as 14 hertz and the intensity or volume, the decibels, up to 200. In fact some whales can have blubber that measures up to 11 inches thick! Echolocation is when mammals produce sound waves and listen to the echoes that return from objects around them. Endangered Species Act.

Their baleen consists of 260 to 400 black, coarse, broad, overlapping plates hanging from each side of the upper jaw. One of the most important senses a whale has is its sense of hearing. Body language may include swimming in a synchronous pattern, slapping their pectoral or tail fins on the surface of the water, or jumping out of the water and landing on their sides, a behavior known as breaching. 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.
