Tree ChartAnatomy of a TreeThe outer bark is the tree's protection from the outside world. Continually renewed from within, it helps keep out moisture in the rain, and prevents the tree from losing moisture when the air is dry. It insulates against cold and heat and wards off insect enemies.

The inner bark, or phloem, is pipeline through which food is passed to the rest of the tree. It lives for only a short time, then dies and turns to cork to become part of the protective outer bark.

Blue WhalesBlue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet (30 meters) long and upwards of 200 tons (181 metric tons). Their tongues alone can weigh as much as an elephant. Their hearts, as much as an automobile.

Blue whales reach these mind-boggling dimensions on a diet composed nearly exclusively of tiny shrimplike animals called krill. During certain times of the year, a single adult blue whale consumes about 4 tons (3.6 metric tons) of krill a day.

Blue Whales continuedBlue whales are baleen whales, which means they have fringed plates of fingernail-like material, called baleen, attached to their upper jaws. The giant animals feed by first gulping an enormous mouthful of water, expanding the pleated skin on their throat and belly to take it in. Then the whale's massive tongue forces the water out through the thin, overlapping baleen plates. Thousands of krill are left behindand then swallowed.

Blue WhalesThe blue whale is the largest animal known to have ever lived on Earth and is the largest mammal in the world. These massive creatures are hefty from the moment they are born and continue to add to their girth throughout their first year. A blue whale calf weighs two tons (1,814 kilograms) at birth and gains an extra 200 pounds (91 kilograms) each day of its first year.

Blue whales are able to breathe air, but they are very comfortable in the ocean waters where buoyancy helps to support their incredible bulk.

These mammals are found in all the world's oceans and often swim in small groups or alone. They usually spend summers feeding in the polar regions.
