Blue One Size
There are some very well known facts blue whale, as that is the largest mammal on earth. There are also some things that are less known. For example, how big they really are. The longest blue whale recorded was a female who was captured in the Antarctic and measured 108 feet from nose to tail. Probably weighed about 150 tons. A more normal weight than a blue whale in the Southern Hemisphere is 80 to 100 tonnes. In the northern hemisphere tend to be somewhat smaller, and would rare to find one more than about 80 feet in length.
When it comes to food, we would expect the largest mammal on the planet to eat something pretty important in the food chain. One of the most striking of the blue whale is about your diet. Not only Do not eat large fish, but opting for some of the smaller fish and live almost exclusively on small shrimp like animals called krill. Needless to say, they have to consume a good number of these krill to meet their dietary needs and can get through about 40 million dollars a day. That's about 4 tons – the same weight as a Ford Excursion.
One of the saddest facts of the blue whale is in relation to their numbers. The early whalers were unable to hunt the whale, because of their size. It was too big to be able to treat successfully. However, once the whaling improved the design of their spears and learned to inflate the whales so they do not sink after being shot, their number decreased dramatically. In a season that was reported killed 29,000. This was in 1931 when his slaughter was at its most prolific. The economy of the use of the blue whale meant that had become a coveted commodity, with a decent size to 120 channel resign barrels of oil. Only after that 99% of the blue whale population had been slaughtered by the Commission IWC banned the hunting of mammals and gave total protection to the right. This was in 1966 and still there are only about 8000 to 14,000 living on the planet.
The gestation period of a whale is 12 months and calves are usually born 2 to 3 years apart. Therefore, its increase of the population will be a slow process. His maturity is measured by the size rather than by age. For example, they reach sexual maturity between 74 to 79 feet. Their young are once weaned reach 52 feet. This is another of those wonderful blue whale facts that most of us are unaware.
Because these funny weight Heavy mammals are not usually visible to us, many of us think of them as almost mythical. It's hard to imagine that creatures of this size living in the same planet and be out of sight. There are many blue whale facts that will fascinate and the more we learn about these graceful giants most of their chances of survival, despite our past mistakes ignorant.
