Facts On Blue Whales: Adaptation And Survival

Blue whales probably are some of the most fascinating creatures in the world. Even though in time this species changed a lot, blue whales still remain famous for their enormous size. Blue whales can easily adapt to the natural environment, but their numbers have been deeply affected due to human action, mostly in the 20th century.

Still, nowadays, various programs aim to help blue whale population grow. Such efforts have led to positive results, as the numbers of blue whales left in the world seems to have grown. Below you can find some interesting facts on blue whales and their habitat. Learning them will help you find out everything worth to be known about this unique species.

Extinction

Blue whales are known as the largest living animals on Earth. They can reach impressive dimensions, some individuals having a length of no less than 100 feet. There is no wonder after all that blue whales live only into the ocean. Having under consideration these dimensions and the environment in which blue whales live, we can surely say that there are just few predators who can attack them. Blue whales tend to spend much of their time in polar waters. Well, this means that the reason why blue whales have been close to extinction is actually linked to the fact that they have been hunted by humans.

Size. Movement. Feeding

Blue whales can store a lot of energy as fat, such as most large animals. So, blue whales can eat a large amount of food and store it for a long period of time, in which they can survive without eating at all. These animals are highly vocal, emitting numerous sounds while traveling. They can travel up to hundreds of miles. The sounds that blue whales make are actually a form of communication. Most commonly, blue whales swim alone or with one other whale. There are very few the cases in which they are seen in large groups.

As you can see, blue whales are absolutely fascinating animals. This species impresses with its size, but also with its characteristics. Blue whales have been close to extinction, even though the species was threatened by humans, mostly. Nowadays, the population of blue whales is in continuous growth, so we can surely say that they are close to no risks of extinction, at least for now.

Why Are Blue Whales Endangered?

Blue whales are the largest animals that live on Earth. They are spectacular both when it comes to their looks and when referring to their size. The largest blue whale is able to reach 100 to 120 feet. Only its tail is of 15 to 20 feet. Despise their unique features, blue whales are endangered animals. In fact, due to their large sizes, blue whales have managed to draw the attention of humans.

The blue whale was included on the International Union for the Conservation of Nature and Natural Resources Red List in the year 1960. It continues to be endangered.

Why are blue whales endangered?

1. Whaling

Blue whales have probably become endangered due to their large size, which manages to draw the attention of humans towards them. Whale hunting is believed to be the main reason why there are only few individuals from the species left. Whaling much diminished the number of whales left in the world’s bodies of water. The size of these whales made them extremely attractive to hunters.

For long time mariners have actually believed that blue whales, being very big animals, could represent a deadly threat in the sea. However, this period known as early whaling did not cause the species to be endangered, as the limited known techniques to capture these animals made the damage produced to blue whale population controllable.

Starting with the 1930s, things changed. Powerful weapons started to be used, an impressive number of whales being hunted each year. Only in 1931 29,649 whales were killed. As numbers increased over the years, the species easily became endangered.

2. Natural causes

However, hunting may be the most important factor leading to this situation, but it is not the only one. Blue whales have a very slow rate of reproduction. A female blue whale can only give birth once at every two years, and to a single calf.

Blue whales usually live in cold environments, so they can easily be injured by ice. Even though blue whales shock with their impressive dimensions, they can simply become victims of other inhabitants of the ocean. Blue whales can be hunted by killer whales.

3. Fishing equipment

Fishing equipment may also cause many whale deaths. Blue whales can easily entangle in fishing gear. As they can get seriously injured, fishing equipment is believed to be one of the main causes which has lead to the death of many blue whales.

A protected species

Having all these facts under consideration, in 1966 the International Whaling Commission declared blue whales a protected species. Since that moment hunting blue whales was banned.

Despite the measures taken to increase the number of blue whales existent in sea waters, this population is still endangered. Heavy sea traffic, sea accidents and other man’s sea activities cause injuries and deaths within the blue whale population every year. Statistics actually show that only 12,000 to 15,000 blue whales still exist in world’s waters nowadays.

Discover A Magical Creature Through Videos

Blue wales are amazing creatures, that are rather unfamiliar to people, do to the fact that their research is quite difficult. Even so, they are fascinating, beautiful and absolutely enormous and you can learn a lot about them by simply looking at the following videos.

The second video is a news footage in which a lucky group of tourists had the opportunity of their lifetime when they were surrounded by several blue wales during a tour.

Last year, a great colony of blue wales was seen near Sri Lanka and researches started on these. In the following video, you can see the footage taken for the scientific study done on the beautiful blue whales.

With all the new information discovered with the help of these videos, you can see the fact that people are trying to get to know the amazing blue wales as much as possible, but the difficulties that arise in the studies still stand in the way of getting to know more and more about these beautiful creatures.

Container Ship Kills a Blue Whale in the Indian Ocean

Blue whales are some of the most fascinating creatures that have ever lived on this planet. They are impressive not only in size (being the largest animals ever known to have lived on Earth), but also in behavior. This is why it is such a shame that whales are severely hunted and have become endangered species. Not only are they hunted, but they are also killed in numerous accidents that take place due to container ships. Unofficial figures show that thousands of whales have been killed by container ships. The number of whales living nowadays hardly reaches 12,000, according to a 2002 statistic. Since then, numerous other whales have been hunted or killed.

This is the case of a blue whale which died just a couple of days ago (on May 11, 2012) after being hit by a huge container ship. The accident happened in the Indian Ocean, just off the coast of Sri Lanka. The poor thing was resting at the ocean surface and did not know what hit her, literally. The busy ship struck the whale during the night. In the Sri Lanka area, huge ships travel at high speed during both daytime and night time, which is why numerous such accidents happen on a frequent basis. Given the impressive size of the whale, you are probably wondering how can a ship kill such a giant. Well, despite being huge, whales do not stand a chance in front of a fully loaded ship and there is no way of them surviving a direct hit. The picture of the whale was captured by diver Tony Wu, who wanted to show the whole world how whales are often killed by devastating ship strikes.

He also said that when a whale is hit by a big ship, the impact is so high that it would not even register. It is just like a tractor hitting a butterfly. As numerous similar cases go unrecorded, people have no idea of how endangered blue whales are. More often than not, they are considered collateral damage and the accident is forgotten right away. This means that tragedies like this happen all the time, without ordinary people even finding out about them. And since most container ship are fully loaded with consumer goods such as cars, appliances and electronic goods, most people do not even care. Something needs to be done about this aspect, though. Otherwise, the number of blue whales will decrease even more and they will eventually become extinct.
