The oceans seem endless and can be very deep and they have a habit of making humans look very insignificant. There are many creatures in the seas which are all beautiful in their own way however there are some that are dangerous to humans while some are very gentle creatures. The Blue Whales are one of these animals that you can find in the deep blue oceans and these particular whales are said to be the biggest animals that have ever existed. The can grow up to 35 meters in length or more and have been in our waters for hundreds of thousands of years. The blue whales are one of the animals that are in danger in the water not from predators but from humans. The Japanese and Norwegian whale hunters go out every year killing any whale they come across which has greatly decreased the number of many whale species.
The Blue Whale is a marine mammal which means that it gives birth to live young and does not lay eggs like other fish species do. All whales give birth to live young otherwise their eggs would be in very big danger because they were so big. These animals are so big that they can weight over 150 tones and a little baby whale that is new born can be four or five times the size of your average car. There are three species of the Blue Whale known from their habitats which are in different oceans for each species. The Indian and South Pacific Oceans hold a species each while the Pacific holds its own whale species. Even though the blue whales are the largest animals on earth they are known to feed of one of the smallest crustations in the sea called krill.
Like all the other fish in the sea the blue whale has a very simple body which consists of a head, body, tail and fins. The bone structure of the whale is relatively like other fish with the main bone being the skull and then a vertebra as well as ribs. Their fins are used to maneuver however the great blue whale takes some time to turn itself around. The breath air out of their blow hole like most other whales which means that they must stay close to the surface. The blue whales can hold their breath for many hours however if they cannot reach the surface because of ice then they will drown like any other air breathing animal. The blue whales only give birth once a year and the offspring has only a fair chance of survival. This is why the population needs to be protected until the numbers of the blue whale increase.
