Whales.
whales travel to cool waters near the Arctic or Antarctica every summer. They feed on krill , small animals that look like shrimp. In the winter, baleen whales head for warmer waters near the equator tobreed. Other whales do not migrate. Narwhals, for instance, live year-round in the cool waters of the Arctic andNorth Atlantic oceans. HAVING BABY WHALES After male and female whales mate, it takes from 10 to 16 months for a baby whale to form. The lengthof time depends on the whale species. A wh...

Whale - biology.
III BEHAVIOR OF WHALES Studies of whales in captivity have taught scientists much about the complex social behavior of whales. Since the late 1980s, advances in the use of satellite trackingsystems have also broadened opportunities for scientists to observe how whales behave in the wild. A Swimming and Diving Whales swim by making powerful up-and-down movements of the tail flukes, which provide thrust. The power comes from body muscles that flex the lower spine upand down in a wavelike motion...

Blue Whale - biology.
Mature females may give birth once every two or three years. The gestation period lasts about 11 months. A single young is usually born the following spring; twins arerare. The females migrate to warm regions to give birth. The young nurse for seven or eight months, gaining as much as 90 kg (200 lb) per day. VII CONSERVATION STATUS Blue whales were not targeted by the whaling industry until the late 1800s after faster steam-powered ships were developed. The peak slaughter of blue whalesoccurre...

Killer Whale - biology.
V REPRODUCTION Mating occurs more often among killer whales of different pods to avoid inbreeding within pods. About 16 to 18 months after mating, females give birth to a single calf.Newborn calves weigh about 200 kg (440 lb) and are about 2.5 m (8 ft) long. Mothers nurse their calf for 14 to 18 months, although mothers continue to be protectiveof their young long after the offspring have been weaned. Scientists do not know how long killer whales live in the wild. Scientists estimate that male...

INTRODUCTION
Herman Melville
These lines (recited by an actor) begin the novel Moby Dick (1851), by Herman Melville.
short novel Billy Budd in manuscript form. Melville’s death in New York City on September 28, 1891, went virtually unnoticed. None of his books was still in print. VI MELVILLE’S EARLY WORKS With the exception of Mardi , all of Melville’s early books are narratives of maritime adventure based upon his own experiences and on his wide reading. Although London publisher John Murray accepted Typee for his Home and Colonial Library as a strictly factual account of South Seas travel, he was lar...

information in Omoo , but various religious groups condemned both books for their unfavorable comments on the work and insensitivity of missionaries in the South Seas. Mardi is a philosophical allegory framed by another adventure at sea. The book’s hero, accompanied by characters representing the intellect, poetry, history, and philosophy, searches the world for universal truth. The book is filled with descriptions—intended as allegories—of human customs, religions, governments, and historical...

Shark - biology.
Sharks have two-chambered hearts that are relatively small compared to the rest of their bodies. Blood flows from the heart to the gills, where it collects oxygen fromwater and then distributes it to the other organs and tissues. The small heart produces weak blood pressure, and many sharks must swim continuously to create themuscular contractions needed to circulate blood throughout their bodies. Most sharks are cold-blooded—that is, they do not generate heat by digesting food. Instead, the bod...

Mammal - biology.
On land, mammals live in many different habitats, and at a wide range of altitudes. Many mammals dig burrows as refuges or as places to raise their young, but somehave developed a largely subterranean lifestyle, feeding on small animals or plant roots beneath the soil's surface. These animals, including moles and mole-rats, digthrough the ground either with spadelike front paws or with their teeth, and they detect danger by being highly sensitive to vibrations transmitted through the soil.Most m...

Dolphin (aquatic mammal) - biology.
Scientists have observed dolphins displaying three types of caregiving behaviors: standing by, excitement, and supporting. In standing-by behavior, dolphins remain inthe vicinity of an injured or ill companion without offering aid. In excitement behavior, dolphins swim swiftly in circles around an injured dolphin, responding aggressivelytoward threats to the injured animal. For instance, they may bite harpoon lines or charge boats that come too close to the animal. In supporting behavior, one or...

A few other species such as ringed seals and harbor seals have been found livingyear-round in lakes and rivers near the coasts of Russia, Canada, and Alaska. IV DIET OF SEALS Most seals eat fish and sometimes squid. The leopard seal, an Antarctic species, may have the most diverse diet of all, commonly hunting penguins and other seabirds,smaller seals, as well as fish, squid, krill (small shrimplike crustaceans),...

Nunavut - Canadian History.
The Arctic Lands is a complex geological area that is centered on the Arctic Ocean. It includes coastal plains, plateaus, and mountains. Coastal plains and plateaus arefound in the western Northwest Territories section of the Arctic Lands, such as on Victoria Island, which is mostly a large, flat plateau. In striking contrast to theserelatively gentle landscapes, the eastern Nunavut section of the Arctic Lands is dominated by a jagged chain of ice-covered mountains. The mountains on EllesmereIsl...

During the Wisconsin Ice Age,alpine glaciers covered the Cordillera, and the movement of the glaciers created razor-sharp peaks and ridges in these mountains. The moving glaciers also createdbroad U-shaped valleys.

Animals.
All animals must breathe oxygen to stay alive. They must breathe out a waste gas called carbon dioxide. Some animals breathe through lungs. Lungs take oxygen out of air. Cattle, dogs, cats, whales, people,and other mammals breathe through lungs. Birds and reptiles also breathe air through lungs. Lungs cannot take air from water. Seals, whales, dolphins, and other mammals that live in waterbreathe through lungs. They can stay underwater a long time because they can hold their breath for along tim...

From Moby Dick - anthology.
'My song for ever shall recordThat terrible, that joyful hour;I give the glory to my God,His all the mercy and the power.' Nearly all joined in singing this hymn, which swelled high above the howling of the storm. A brief pause ensued; the preacher slowly turned over the leaves of theBible, and at last, folding his hand down upon the proper page, said: 'Beloved shipmates, clinch the last verse of the first chapter of Jonah—'And God had prepared agreat fish to swallow up Jonah.' 'Shipmate...

Iceland - country.
III PEOPLE Icelanders are one of the most homogenous peoples in the world. They are predominantly of Nordic origin, descendants of the hardy people who emigrated fromNorway to Iceland in the Middle Ages. There are also some Celtic influences from Irish and Scottish immigrants who arrived from the British Isles ( see Celts). The population of Iceland (2008 estimate) is 304,367. Numerous times in its history, Iceland has suffered major population losses due to epidemics, volcanic eruptions, and...

noises to find mates and scare away rivals. Some types of seals sing songs that last more than a minute. ARE SEALS ENDANGERED? Large sharks and killer whales hunt and eat seals. Polar bears kill seals on land and on ice in the Arctic.But people are the biggest threat to seals. People have hunted seals for food, skins, and blubber. The northern elephant seal has nearly died out. Hawaiian and Mediterranean monk seals are alsoendangered, and a third type of monk seal is already extinct. Many countr...

Inuit.
VII HOUSING, TRANSPORTATION, AND CLOTHING Inuit homes are of two kinds: walrus or sealskin tents for summer and huts or houses for winter. Winter houses are usually made of stone, with a driftwood orwhalebone frame, chinked and covered with moss or sod. The entrance is a long, narrow passage just high enough to admit a person crawling on hands and knees.During long journeys some Canadian Inuit build igloos, winter houses of snow blocks piled in a dome shape (the term igloo comes from the I...

Arctic - Geography.
The Arctic is not a frozen desert devoid of life on land or sea, even during the cold, dark winter months. Spring brings a phenomenal resurgence of plant and animal life.Low temperatures are not always the critical element—moisture, the type of soil, and available solar energy are also extremely important. Some animals adapt well toArctic conditions; for instance, a number of species of mammals and birds carry additional insulation, such as fat, in cold months. Arctic summers with extended dayli...

Comparative Anatomy.
In comparing two species, anatomists have to be careful to differentiate between homologous structures, which are ones that have evolved from a shared ancestor, andanalogous structures, which have developed from different origins. Homologous structures are built on the same underlying plan. A human arm, a bat’s wing, and awhale’s flipper look quite different from the outside, but the bones inside reveal that these limbs all have the same basic structure. Analogous structures, by contrast,often l...

Antarctica - Geography.
The maximum area of sea ice surrounding Antarctica each winter varies from year to year. A marked decline during the 1970s appears to have reversed in more recentdecades, except in the Antarctic Peninsula area. This area has lost almost 40 percent of its sea ice since the start of the 1980s. Sea ice is important to marine life. Krillfeed on algae that live under the sea ice and are released when the ice melts in spring and summer. In turn, many marine animals feed on krill. Emperor penguinsbreed...
