North Atlantic Right Whale
Over a thousand whales are killed each year for their meat and body parts to be sold for commercial gain. Their oil, blubber, and cartilage are used in pharmaceuticals and health supplements.
List of extinct cetaceans. However, the Atlantic population of gray whales (Eschrichtius robustus) became extinct in the 18th century, and the baiji (or Chinese river dolphin, Lipotes vexillifer) was declared "functionally extinct" after an expedition in late 2006 failed to find any in the Yangtze River.
By the late 1930s more than 50,000 whales were killed annually. In 1986, the International Whaling Commission (IWC) banned commercial whaling because of the extreme depletion of most of the whale stocks. Contemporary whaling is subject to intense debate.
Conservation Information
The Endangered Species Act also protects blue whales. The present population worldwide is estimated to be 15,000 whales; with 2,000 of these living in CA coastal waters.Whaling is the hunting of whales for their usable products such as meat and blubber, which can be turned into a type of oil which became increasingly important in the Industrial Revolution.
Today, the range-wide population is estimated to be at least 13,000 manatees, with more than 6,500 in the southeastern United States and Puerto Rico. When aerial surveys began in 1991, there were an estimated 1,267 manatees in Florida.
"Blue whales have now been increasing by about 7-8% per year for the last 10 years at least, for which we have good data. The IWC believes the global population of blue whales, which grow to 30 metres long and weigh up to 200 tonnes, is around 4,500.
1. 16,000 whales have been murdered every year for 83 consecutive years. Whaling has been around for centuries, but due to a rapid increase in demand for whale meat in certain countries, whaling practices went into overdrive at the turn of the last century.
Top 10 Extinct Animals
- Sabre-toothed Cat. Often called Sabre-toothed Tigers or Sabre-toothed Lions, they existed 55 million to 11,700 years ago.
- Woolly Mammoth. An enormous mammal, believed to be closely related to the modern-day elephant.
- Dodo.
- Great Auk.
- Stellers Sea Cow.
- Tasmanian Tiger.
- Passenger Pigeon.

In general, dolphins and whales have two basic ways of sleeping, according to Scientific American. They either “rest quietly in the water, vertically or horizontally, or sleep while swimming slowly next to another animal.” Sperm whales, for instance, have been photographed floating vertically with their tails down.
Killer whale attack. Killer whales (or orcas) are powerful predators capable of killing leopard seals and great white sharks. They have also been recorded preying on usually terrestrial species such as moose swimming between islands. In the wild, there have been no fatal attacks on humans and only one reported bite.
The small sea creatures that baleen whales eat are small crabs, octopuses, zooplankton (tiny animals floating in the water), fish, krill (which are similar to shrimp), and various crustaceans. Fin whales eat a variety of schooling fish, crustaceans, and squids. Blue whales mostly eat krill.
Historical estimates indicate that widespread commercial exploitation began in the 19th century and that approximately 20,000 humpbacks and 30,000 to 50,000 fin whales existed in the North Atlantic before hunting began (2, 9, 31–33).
Leatherback turtles are listed as endangered on the Species at Risk List in Canada, and are on the Endangered Species List in the United States. There are estimated to be between 34,000 and 36,000 nesting females left worldwide (compared to 115,000 nesting females in 1980).
Whaling is the hunting of whales for their usable products such as meat and blubber, which can be turned into a type of oil which became increasingly important in the Industrial Revolution.
Pre-whaling population estimates were over 350,000 blue whales, but up to 99% of blue whales were killed during whaling efforts. Presently, there are an estimated 5-10,000 blue whales in the Southern Hemisphere, and only around 3-4,000 in the Northern Hemisphere.
These whales will be extinct in 25 years, scientists say — unless we act now to save them. PROVINCETOWN, Mass.
Is the blue whale extinct?
Endangered (Population increasing)
The hunting of whales on an industrial scale began in the 17th century and into the 20th century, and as a result of the quantities caught the whale is an endangered species. The International Whaling Commission (IWC) banned commercial whaling in 1986 to increase the remaining whale population in the seas.
The blue whale is found alone or in small groups in all oceans, but populations in the Southern Hemisphere are much larger. In the Northern Hemisphere, blue whales can be seen regularly in the Gulf of St. Lawrence and off the coasts of Monterey, California, and Baja California, Mexico.
There are 16 populations of humpbacks around the world. Four of them are considered endangered and one is threatened. The global population has been rebounding since whaling was banned in the 1970s. It's estimated there are currently between 120,000 and 150,000 humpbacks.
Blue whales filter their food through their baleen plates. Blue whales eat krill (euphausiids) and copepods. A blue whale can eat up to 8,000 lbs. of krill during its peak consumption period.
The 2018 hunt led to 333 minke whales being killed in the Southern Ocean, including 122 pregnant females.
Japan maintains that annual whaling is sustainable and necessary for scientific study and management of whale stocks, though the Antarctic minke whale populations have declined since the beginning of the JARPA program and those whales killed have shown increasing signs of stress.
Commercial whaling ceased for a five-year period to allow a small scientific catch for gauging the stock's sustainability; whaling subsequently resumed in 1993. Minke whales are the only legally hunted species.
Whales use blubber as an insulation layer to help maintain the energy and warmth when they dive to cool depths or travel to cold waters such as in Alaska. The blubber layer is a thick (6 inches) layer of fat that is found under the skin.
In 2016, according to the country's Institute for Cetacean Research, Japan's whaling fleet has killed 333 minke whales in the part of this year's Antarctic whale hunt. Some 230 were female; about 90% of these were pregnant, according to the report.
The animals are losing their ability to replace their dead. And for such slow-to-mature, slow-to-reproduce animals, a trend like that can go on for only so long. “At this rate of decline, they're estimated to be functionally extinct in just a few decades,” says Kershaw. The Simpsons may outlast them.
The minke whale continues to be hunted in nations such as Iceland, Norway and Japan. Minke whales are listed as a species of least concern by the IUCN Red List in part due to a lack of data. Some of their populations have experienced declining numbers, but not enough to indicate that they are in danger of extinction.
