How Many Whales Are There?
If you want to know how many humpback whales there are, one thing you should do is to find out their population status. There are a number of different methods used to track down the information, but all of them are only as good as the information you are able to get. If you are interested in finding out how many humpback whales there are, read on to find out how.
Until recently, it was believed that there were only two known populations of humpbacks, located in the Southern and the Northern parts of Australia. There are a few coastal communities that seem to be the only areas where these whales are caught and brought into the marine park. In fact, there are reports from up to six times more whales in the Northern region than in the Southern regions. The numbers seemed to indicate that the whales hunted for food in the Northern region were much larger than the ones in the Southern region. It was also believed that whales, which were primarily found in the coastal areas, were not as active as those in the open ocean.
In recent years, with the help of modern technology and better oceanographic equipment, researchers have been able to detect the location of whales using sonar. This method has been especially useful in finding the whales’ migration paths. This information has enabled specialists to accurately pinpoint how many humpback whales are there in certain areas. As well, it has been possible to estimate how many whales are able to reach a particular size and weight in specific waters, when and how fast they can swim.
A new study by the Antarctica Research Centre at the University of New South Wales in Australia, has put forward a theory about why whales behave as they do. The Australian researchers believe that the whales use temperature changes, food availability and their migratory patterns to calculate their age. According to the study, whales start reproducing at an earlier age when ocean temperatures start to warm up. They then migrate into calmer waters where temperatures remain low. In addition, whales have also been seen to be particularly choosy when it comes to their feeding grounds.
With the loss of whales’ prey and predators over the years, the number of mature female whales is reduced. It is believed that the decrease in the original population of whales may be linked to the decline in the whaling industry in the 1800s. International trade in whale blubber caused a reduction in the number of whales that could be harvested, causing a population decline as well. The Australian scientists believe that the reduction in the whale’s original population can result in the formation of new types of whales, in other to marine environment, and possibly push the equilibrium between the two populations.
How many Whales are there? Experts estimate that the number is up to five million. However, no precise numbers have been given, since the exact population figure will depend on how many humpback whales there actually are, as well as how many of these are mature females. If you want to find out more about how commercial whaling is affecting the world’s marine life, then pay a visit to the Humane Society of the Pacific. They will be conducting a special whale watching program this spring.
