The latest findings from scientists have found that the world's smallest whale, Wajita, is in a very difficult living environment, and if it is not rescued, this species of whale will face extinction.
Wajita "lives in Mexico, where many calves are trapped and life-threatening because locals often cast nets into the water to kill fish and shrimp."
According to the statistics of the local Whale Research Society, there are currently only 250 to 400 whales of this species left in the world, which is a lot lower than in previous years, and at least 39 to 78 small whales are entrapped, which far exceeds the annual birth rate of this whale.
Another way of putting it.
There are more than 90 species of cetaceans in the world, which can be roughly divided into two groups, baleen cetaceans and toothed cetaceans. Baleen whales are large and feed on plankton in the sea, with the blue whale being the largest living animal on Earth. Toothed whales are generally relatively small in size and feed on marine mammals such as fish or seals, among which small toothed whales are collectively called dolphins, and the finless porpoise living in the Yangtze River in China is the smallest whale in the world.
I don't know how many people are.

The smallest shark is the dwarf horn shark, small enough to fit in your hand. It's about 6 to 8 inches long and weighs less than a pound.
The skeleton of a shark.
All sharks have a body of cartilage. The skeleton of a shark is made of cartilage, not bone. Cartilage is lighter and more elastic than bone. All sharks belong to the class Sharks, and all Sharks have cartilage.
What is the size of a shark?
Sharks range in size from as small as 6 inches in length to as large as 18 meters.
Whale sharks are the largest fish in the sea and can reach up to 60 feet in length when they reach adulthood. Despite its large size, the whale shark has the smallest teeth among sharks. The smallest shark is the dwarf horn shark, small enough to fit in your hand. It's about 6 to 8 inches long and weighs less than a pound.
The largest fish in the world is the whale shark. It can be up to 18 meters long and weigh up to 40,000 kilograms. Luckily, their diet is plankton, otherwise, humans would be in trouble!

Summary. The Gulf porpoise is a species of porpoise that lives in the northern Gulf of California, and they do not belong to the dolphin family to be exact, but they are the smallest of the cetaceans, with an average adult length of less than a meter. The Gulf porpoise is nearing extinction, with only 30 left in the world.
Hello, thank you for using and knowing, here is the best solution for you, here is this question by me I am inquiring for you here, please wait a moment Ha The message is being reviewed, it may be a little unable to reply in time, please wait a moment to kiss <>
Hello <> The smallest whale in the world is: the Wajita whale.
Wajita whales. Average adult length: male centimeters, female centimeters.
Adult weight in kilograms. Newborn pups grow rice. It inhabits the sea at a depth of 11 50 m and 11 25 km from the shore, with silt and clay at the bottom.
In particular, it prefers muddy water, which is highly nutritious.
How many meters long. Dear I hope the above is helpful to you If you are satisfied with me, please give a thumbs up <>
Finally, I wish you a happy life and a prosperous business <>
<> if you still have questions, you can ask me after the consultation

<> "The vaquita is an endemic species of raw lead oak that lives in the Gulf of California.
They are the smallest whales in the world, with the female vaquita measuring about 140 centimeters and the males slightly smaller at about 135 centimeters.
Usually vaquitas like to move together in pairs and threes, and sometimes they will form large groups of more than a dozen.
They live in shallow waters and rarely go to depths of more than 30 meters. This habit is related to their diet, with vaquitas eating squid, small fish and crustaceans, which usually live between 11 and 25 kilometres from the coastline, where they are rich in nutrients washed down from the continent and are relatively turbid for survival.
Since the large-scale human movement in the Gulf of California, the habitat of the vaquita has been seriously threatened, and the number has been decreasing year by year. By the 1930s, the vaquita population had dwindled to 150 to 300 individuals.
This has since been increased under local conservation measures, and by 1997 it had risen to 567 heads. However, the frenzied illegal fishing frenzy has pushed the species to extinction at an annual rate of 18 percent. By 2014, the number of people in the field had been reduced to 85.
In addition to the decline in numbers, inbreeding has also made vaquitas less and less adaptable, which makes it very difficult for the population to recover.
According to a report released in February 2017, the vaquita population has dropped to about 30 individuals. However, in July 2017, the head of Mexico's environmental agency announced that there are still about 100 vaquitas living in the Gulf of California.
Even so, it is difficult to change the precarious situation of the species. At present, the only hope is placed in an animal rescue agency based in Victoria.
The agency is trying to increase the population of vaquitas by means of artificial breeding.
