Whales are a mammal that lives in the ocean and belongs to the order Cetaceans.
They are one of the largest animals in the world, with a body length of 30 meters and a weight of 200 tons. Whales can swim underwater for up to 30 minutes and dive to depths of up to 2,000 meters, making them apex predators in the ocean. In addition, whales are highly social animals, they usually live in groups, with complex social structures and behavioral habits.
Distribution and conservation status of global whale resources:
The distribution of global whale resources is mainly concentrated in the Arctic seas, Antarctic seas and tropical waters, the most famous of which is the Antarctic whale. Due to factors such as overhunting, environmental pollution, and climate change, many whale populations around the world are on the verge of extinction, such as blue whales, arctic whales, killer whales, etc., in addition, the number of some whale populations is also declining, such as humpback whales, sperm whales, etc.
In order to protect whale resources, the international community has taken a variety of measures, such as banning commercial whaling, protecting whale habitats, and reducing marine pollution. In addition, some scientists and environmental organizations are also actively researching and promoting new conservation technologies and methods, such as the use of non-lethal whaling methods and the use of bioacoustic monitoring technology, in order to better protect whale resources and marine ecosystems. <>

Whales can live up to about 100 years at most, they belong to the long-lived marine organisms. However, the lifespan of different species of whales is also different, for example, the lifespan of killer whales will be relatively short, only about 30 years.
The lifespan of blue whales will be relatively long, about 80 years, and some can even reach 100 years. In addition, human hunting and environmental pollution will have a certain impact on the life span of whales.
Body length and weight of different whale breeds:
Different species of whales have different body lengths, and the common killer whales, they are not very large, and their body length will be between 8-10 meters after adulthood. However, they have a ferocious personality and are already at the top of the marine food chain.
Then there are sperm whales, which can reach between 11-20 meters in length and 24-45 tons in weight. Blue whales are larger, with the largest known blue whale being around 33 meters long and weighing around 180 tons. However, their length is variable and variable, and is affected by the environment and other factors.

The lifespan is 50 to 100 years.
As the longest-lived animal in the myth of the old man, the whale has a life of about 500 to 1000 years in the myth, but this is a myth after all, the highest lifespan of our whales in the ocean can reach 50 to 100 years, and as a relatively scarce blue whale, its lifespan can reach at least about 80 years.
However, in reality, our oceans are also polluted, and the survival of marine creatures has been in danger, and our whales generally have a lifespan of only about 30 years, which is sad that such a value is different from the original lifespan value.
Characteristics of whales as well as lifestyle
Whales need plenty of food** to sustain their large bodies, and most species of whales are carnivores, feeding on krill, plankton, and small fish. Baleen whales, such as humpback whales and blue whales, have baleen plates in their mouths that can filter large amounts of food from the water, and toothed whales, such as killer whales and sperm whales, use their teeth to catch and eat their prey.
Many species of whales are migratory, making long journeys between feeding and breeding grounds, and they often prefer areas with deep clear water, strong currents, and stable temperatures, and some species, such as beluga whales, even live in estuaries and river systems.
Many species of full-yearling whales are highly social and live in groups known as pods, where whales communicate through a complex vocal system that includes songs, clicks, and whistles.

Different breedsWhalesLifespan is different, like:Killer whalesThe lifespan is 20-40 years, and the lifespan of a blue whale is 80-100 years.
The rate of substance metabolism in cetaceans.
It is very high, so the lifespan is not too long compared to other large animals, the average lifespan is only 30 years, and the longest lifespan is not more than 100 years. Killer whales have a lifespan of 20-40 years, beluga whales.
The lifespan of baleen whales is generally 30 to 40 years, baleen whales generally live for 40 to 50 years, and blue whales have a lifespan of 80-100 years.
Whales
The whale is a mysterious and ancient creature, not a fish, but the largest mammal in the world that we have ever found.
There are many kinds of whales, different species have different habits, almost 98 species of whales have been discovered so far, of which more than 30 species live in China's waters.
Whales are smart, and between them is through "sonar."
to communicate, to locate, to find food, and that way of communicating is surprisingly precise. The whales are a huge family, all of them are very intelligent, and some of the smaller whales are even sent to zoos for training, and they can do some actions that are difficult for other fish to do. Whales are very docile creatures and usually feed on edible substances such as plankton, small fish, seaweed, etc.

There are about 1.5 million heads, 70,000 fin whales, 10,000 camel whales, and 150,000 to several thousand other cetaceans. According to statistics, only 300 whales of the least one species survive in the Atlantic. But this is an estimate, and both the species and the number of whales are a gross estimate, which is very inaccurate.
At an altitude of 150 meters above the sea, researchers counted the number of whales exposed on the surface of the water by the average diving time of whales from small planes, and then calculated the number of whales. Therefore, it is conceivable that the debate between capture and protection is fierce. Norway and Japan, for example, believe that 700 whales per year are no threat to their survival.
There is also a theory in Japan that whales feed on other fish, and that the presence of whales threatens the survival of other fish. But there are few such theories.
Each "grandmother" is raised from a cub and is born into their mother's family, or rather, a matrilineal clan. Family members get together to live, hunt and play, and even communicate through another unique tweet. Whale calves and females live in their matrilineal families throughout their lives. >>>More
Hey, my children, don't think that we whales are fish, if you do, then you are very wrong, we whales are mammals. In addition, I would like to reveal a little secret to those who think I am a fish: I should supplement the biological "nutrition", hahahaha! >>>More
I have a huge white body with soft and flexible white fins. My teeth are big, but they never hurt humans. >>>More
When whales sleep, they always gather together, with their heads facing inwards and their tails facing outwards, floating in a circle on the surface of the sea and spreading out as soon as there is movement. >>>More
