  • Blue Whale imageBlue whales are baleen whales, which means they have fringed plates of fingernail-like material 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 behind and then swallowed.

    What is the color of the Blue Whale?

    Blue whales look true blue underwater, but on the surface their coloring is more a mottled blue-gray. Their underbellies take on a yellowish hue from the millions of microorganisms that take up residence in their skin. The blue whale has a broad, flat head and a long, tapered body that ends in wide, triangular flukes.

    What does a Blue Whale eat?

    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.

    How big is a Blue Whale?

    Earth's largest animal, the endangered blue whale can eat some 4 to 8 tons (3.6 to 7.3 metric tons) of krill per day. Blue 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.
  • Does the Blue Whale make sounds?

    Blue whales are among the loudest animals on the planet. They emit a series of pulses, groans, and moans, and it’s thought that, in good conditions, blue whales can hear each other up to 1,000 miles (1,600 kilometers) away. It is estimated that the blue whale sound source levels are between 155 and 188 decibels.

    All blue whale groups make calls at a fundamental frequency of between 10 and 40 Hz, and the lowest frequency sound a human can typically perceive is 20 Hz. Blue whale calls last between ten and thirty seconds. Blue whales off the coast of Sri Lanka have been repeatedly recorded making "songs" of four notes duration lasting about two minutes each.
  • Why does a Blue Whale make sounds?

    The reason for making the sounds is unknown. There are six possible reasons in discussion:
    1.To know the distance between eachother.
    2.Species and individual recognition.
    3.Information like feeding, alarm, and courship.
    4. Social behavior, like calls between females and males.
    5.Location of topographic features.
    6.Location of prey resources.

    Scientists think they use these vocalizations not only to communicate, but, along with their excellent hearing, to sonar-navigate the lightless ocean depths.
  • How fast does a Blue Whale swim?

    These graceful swimmers cruise the ocean at more than five miles an hour (eight kilometers an hour), but accelerate to more than 20 miles an hour (32 kilometers an hour) when they are agitated.
