Pictures of Blue Whales are among the most famous wildlife photos of all time. It is almost impossible to not be entertained by these creatures. Even people who are totally non-believers at first glance are charmed by the beauty of these creatures. And even if you are not a fan of whales, chances are that you would like to know more about this incredible animal.
Blue Whale Facts – First and foremost, the blue whale, also known as the great white shark, is the largest living mammal on earth, at up to 28 feet long, 11 feet tall and can weight as much as four,500 pounds. They live primarily in the Arctic Ocean, but there have also been sighting off South Africa and other places as well. These creatures are generally herbivores, feeding on fish, squid and small fish. Their range in size affects the amount of food they can eat every day.
The Balaenoptera borealis or the Balaenoptera catesbeiana is the most common type of blue whale. The giant marine mammal has gray, streamlined skin with a soft, white body with four long pectoral fins, which allow the animal to swim fast. Males can reach a length of 18 feet and females can reach a bit over 15 feet. These animals feed on small fish, corals, mollusks and snails.
Pictures of Blue Whales were taken for a very long time before man ever lived on the earth. One of the oldest pictures of blue whales is from Paleocene times. Another example of a prehistoric blue whale fossil is from the early Cretaceous period. We can find fossils of these amazing mammals in sedimentary rock layers that have accumulated over time. Most people think that these mammals only appeared in the later part of the Cretaceous geological period, however there is evidence that they existed in the early Jurassic period.
The north central Pacific Whale is another one of the species represented in this unique group of mammals. The species is usually a great length with a head much larger than its back and a gray body with a dorsal fin very long. These animals have an unusually large brain, which may account for why they can recognize land routes. They live all around the world and although they tend to migrate along coastal areas, they occasionally venture further into the southern hemisphere.
A very interesting group of mammals are the Balaenoptera. This is a very important group of whales with recent discoveries placing them in two separate families. A subfamily is Balaenoptera cadenati, which consists of two subspecies; the first being the common minke and the second is the long-finned bale. These whales tend to be more localized in their geographic areas but they are regularly seen together with other bale whales in certain geographical areas. A recent study has placed the distribution of this whale species in the Bering Sea around Russia and Alaska.
