Whales are the largest living things on earth, reaching 35 meters in length and 150 tons, even with all its majesty these amazing creatures are on the list of most endangered species: Of the 11 species of large whales, at least nine were severely affected by the predatory action of man, according to Sea World.

Right Whale
Right whales can reach up to about 25 feet long and weigh nearly 70 tons, are generally black with patches of roughened skin called callosities on the head.
Although endangered right whales live in the world, scientists believe there are about 350 North Atlantic, North Pacific 100, and a few thousand in the southern hemisphere.

Sperm
The sperm whale is the largest toothed whale, with up to 26 teeth on each side of his jaw giant, estimates say that more than one million sperm whales were captured at the height of the whaling industry.
The whale was included into the Law of Conservation of Endangered Species in 1969, estimated there are between 200,000 and 1.5 million sperm whales in the oceans.

Pilot whale
They are easy to train and are believed to be as smart as dolphins - and they are also very social, often traveling in large groups, according to the American Cetacean Society. They often swim close to shore, it is common to find whales stranded pilots.
This whale was photographed in the Strait of Gibraltar by a group of marine biologists.

Blue Whale
It is believed that this is the first photo of a baby blue whale, the giant baby surprised scientists off the coast of Costa Rica, approaching the boat, according to National Geographic. Typically, protective mothers would keep their children away.
The blue whale is the largest mammal on earth, reaching lengths of up to 80 meters and weighing up to 150 tons.
But its size does not protect them from extinction, with fewer than 2,000 living in the wild worldwide, after a generation of human hunters, they followed us fiercely from 1920 to 1960. Blue whales spend the winter in warm climates and in summer, cooler water - they can eat more than 7,000 pounds of food in one meal.

Humpback Whale
Humpback whales are known for their unique talent - singing. His songs can be heard by other whales, and is used to attract them during mating, during feeding, or in the care of mothers with their babies.
Their style of hunting is also worth noting: Humpbacks work together to corral schools of fish, a whale blowing bubbles against the school forcing them to fall off the trap.

Killer whale
Orca (Orcinus orca) (popularly known as killer whale) is the largest member of the family (Delphinidae) the same dolphin. It is a versatile predator, which can eat fish, shellfish, birds, turtles, though, hunting in groups, able to capture prey of larger size, including walruses and whales. The name killer whale comes from the direct translation of English “killer whale” and, even though incorrect, has become popular, especially among the laity. It is a carnivorous predator, being considered as an Animal Top of the food chain. Can weigh up to nine tons. It is the second largest mammal of geographical distribution (after the man), and can be found in any of the oceans.

Beluga Whale
The beluga whales have a white color due to their adaptation to cold, have a thick layer of blubber that keeps them warm waters of the Arctic and a ridge that replaces its dorsal fin, so you can swim under the ice. Is distinguished from other whales in another respect: the neck vertebrae are fused beluga not, so he can turn his head sideways.

Fin whale
These whales live in oceans all over the planet, where they face a multitude of threats: They end up trapped in fishing nets of fishing vessels, food shortages due to its commercial fishing and poaching (for their hunting has been banned since 1976, though they may still be captured in Greenland).
Fin whales are the second largest whale in the world, with babies born weighing 6,000 pounds, reaching 160,000 as adults.

Gray Whale
Gray whales spend their time moving over western North America from the Arctic Pole to the Lower California, according to the American Cetacean Society - which is where you’ll see them on whale watching expeditions.
If you get close enough, you can also see patches of white barnacles that grow on the whales, and orange whale lice, which feed on the dead skin of whales.

Whale Shark
The whale shark (Rhincodon typus) is the only species of the family Rhincodontidae, is known as whale shark due to its sheer size, live in the oceans warm, tropical climate, besides being the largest species of shark is the largest known fish and can grow to about 20 m and weighing over 13 tons. The animal is completely harmless to humans and feed on plankton by filtering. When he explains that most sharks are not dangerous to humans, this species is used as the primary example. Divers can swim around the giant fish without any problem.
