Blue Whales

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.

Blue Whale ‘Delta’ Reveals Its Unique Fluke

A blue whale nicknamed Delta gave quite a show a few weeks back after being photographed off Dana Point. Onlookers aboard a boat operated by Dana Wharf Whale Watching enjoyed the splash when the blue whale exposed its fluke – or tail – for everyone to see.


The blue whale was affectionately named Delta because of her large tail span. The peculiar shape of its fluke with both ends turned upward, like winglets on an airplane wing, earned the blue whale this great nickname.

Check out this video below and watch the show for yourself! After being posted online, the video became an instant hit. Facebook users started posting comments, sharing where they had seen – or thought they had seen – this particular whale.

According to Cascadia Research Collective in Olympia, Washington, two blue whales with similar fluke formations have been photo-cataloged in the eastern Pacific. The image captured recently off Dana Point, by Frank Brennan of Dana Wharf Whale Watching, was matched to a whale cataloged as #135, as seen in the video above.

Delta is a new whale to me, but others say they’ve seen a lot of her over the years”, said Mike Makofske, a spokesperson for the Orange County chapter of the American Cetacean Society.

I posted Dana Wharf’s photo on the ACS National Facebook page, and Dorris Welch of Sanctuary Cruises in Moss Landing said they’d seen her several times in early summer 2012, up in Monterey Bay. Another poster, Diane Dahl Cullins, commented that she had a picture of the same whale taken two years ago off San Diego”, he added.

Facebook user Eric Zimmerman posted: “On the [Santa Barbara-based] Condor Express we nicknamed it ’747′ after its large size and the way its fluke tips resemble the winglets found on the end of large airplane wings”.


Annie Douglas of Cascadia stated via email that the first known sighting of Delta was on October 7, 1997, in the Gulf of the Farallones beyond San Francisco. Before this recent sighting, Delta had been encountered 15 different years – including two years off Baja California – and 29 times, based on photo matches.

From 1987 to 2005, most encounters were off northern Central California but, interestingly, according to Cascadia’s records, all known sightings since 2007 were off Southern California.

About 2,000 endangered blue whales sail California waters every season, with the 2013 season apparently just getting underway. As it seems, Delta is among the early arrivals.

It’s not clear whether the shape of this blue whale’s fluke is because of a birth defect, but the right tip appears to be more upturned than in previous years. Also, according to Douglas, the sex of this blue whale is not known.

What are blue whales?

Blue whales are the largest animals in the world. They are the largest mammals known to have ever lived on Earth. Blue whales can easily be described as magnificent marine creatures.

What is the diet of a blue whale?

A blue whale commonly weights 200 tons. It is able to reach such an impressive dimension based on a diet that includes almost exclusively krill. Around 4 tons of krill can be consumed by a blue whale a year. Blue whales feed by gulping a huge quantity of water. Then, with the use of its massive tongue, this whale is able to eliminate all water. The krill left behind is then swallowed by the blue whale. Even though blue whales feed almost exclusively on krill, they may also eat copepods.

Where do blue whales live?

Since the blue whale is the biggest animal that has ever lived, there is no wonder that it lives only in oceans. Blue whales can be found in oceans from all over the world, but it is important to know that nowadays this is an endangered species. These animals prefer to live in cold or temperate waters, in the deep of the ocean. They are can be seen in the waters near Iceland and Ireland, the southern Caribbean and the Sea of Cortez, as well as in the Gulf of Alaska.

Why are blue whales endangered?

Blue whales became endangered before the 1960s when commercial whaling was still legal. It ceased in 1964, but the blue whale population has never grown back to its initial numbers. Before the whaling industry went global, blue whale population included more than 270,000 individuals. Currently it is believed that about 10,000 blue whales are left in the world. Hunting, pollution and environmental degradation are considered to be the most important causes why blue whales are endangered.

Who are the predators of blue whales?

Blue whales commonly live 35 to 40 years. They are the largest and the loudest marine mammals on Earth. Blue whales are known to follow seasonal migrations during the winter and summer, both for food and for mating. They have an enormous size, but blue whales can also impress with their speed. So, who are the predators of blue whales? Having under consideration their characteristics we can surely say that blue whales have few natural predators. Man has actually been the most important predator of blue whales. Ship accidents and fishing gear, but also killer whales, can still cause victims in the blue whale population.

Even though whaling is illegal, blue whales are still under threat. Changes in the ocean, oil splits, ship strikes and noise pollution much affect blue whales, contributing to the decrease of their population.

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.

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.
