What is the whale whale?
humpback whales, megaptera novaeangliae is a great whale known for its mysterious song. Humpbacks are found in most earthly oceans and seas and are occasionally objects of legends or worship. It is assumed that there are about 75,000 live cyaks, but the population has never fully recovered from the large whaling industries of the 17th-20th industries. century. They are mostly black, but they can have white patterns on their underside, fins and tail. For identification photographs, distinctive color and comb patterns are used on their fluctions, because no two tails of humpback whales are not exactly similar.
At the birth of the humpback whale, it weighs approximately one ton (907 kg) and is between 10 and 15 feet (3-4.5 m) in length. The mature whale will be between 40-50 feet (12.2-15.2 m) long and weight of 25-40 tons (22 680-36 287kg.) Women are reproduced every two or three years after sexual maturity between five and seven ages. For many years, experts have believed that the average humpback whale has lived 50-60 yearsbut it was found that recent specimens of similar whales are much older. It is now assumed that bumps can live for more than a hundred years.
Whale of humpback whales is classified as a Baleen whale and therefore has no teeth. Instead, they have a number of flexible boards made of keratin through which they can filter their food. Their diet consists of small fish, shrimp and krill. Humpbacks use a hunting technique called Bubble Net Fishing, where the whale group swims in a circle and blows bubbles through their wounds to surround the fish in the ring. After they have closed their prey sufficiently, the whales alternate to throw a circle to swallow Fish.
by forcing the male humpback from air through their whale. Each song lasts between 10-20 minutes and is sung by all men in the regional group. Although all men sing the same song, the pattern of the song can change during the season. In spite ofRyhu extensive studies remain confused with songs. Although theories indicate different functions of songs such as breeding or dominant behavior, no theory has been convincingly proven.
humpback whales have been hunted extensively on the days of a large commercial whale and it is believed that the global population has dropped to 10% of its preliminary levels. Despite the ban on the International Commission for the Whale Commission (IWC) in the 60s of the 20th century, some nations continued to hunt humpback whales for commercial and research purposes. In 2007, Japan announced its intention to kill 50 humpback whales for research purposes and met global protests. Hunting was postponed until the regar of the conference IWCZánostost.
Despite the ban of IWC, the whale of humpback whales remains in danger due to noise and water pollution, collisions with boats and entangling in commercial fishing equipment. Although the population level has been somewhat recovered since the 1960s ban, the species has not yet received preliminary populations and some experts considered them vulnerable inin the future. The popularity of industries for whale monitoring is promising for this species, but experts warn that the measures of conservation of whales must be taken seriously if people intend to protect animals from damage.
