The Shoubi killer whale is a large toothed whale with a length of 8 to 10 meters, a weight of about 9 tons, a slightly rounded head, and an inconspicuous beak; dorsal fin tall and erect, curved up to 1 m; The body is black and white. The wings are far apart. The temporal fossa is large.

The mandible counterpart has a short slide, an elongated mouth, sharp teeth, a fierce temperament, and is a carnivore, but also good at attacking prey. Killer whales are natural predators of penguins, seals, and other animals. Sometimes they also attack other cetaceans, even great white sharks, which can be called the overlords of the sea.

Killer whales are found in almost all areas of the ocean, from the equator to the polar waters. There is no limit to its range by water temperature or depth. The distribution extends to many enclosed or semi-enclosed seas, such as the Mediterranean, the Sea of Okhotsk, the Gulf of California, the Gulf of Mexico, the Red Sea, and the Persian Gulf.

According to the head of the Maritime Administration,The reason for the appearance of Bryde's whales in the waters of Shenzhen is related to China's regulationsAt present, all sea areas in China are entering a fishing moratorium, during this timeFishermen are forbidden to go into the sea to fishA large number of fish appeared in the nearby waters。These schools of fish are the best food for Bryde's whales, and a large number of fish congregate in the waters of Dapeng in Shenzhen, which may beIt attracted the predation of Bryde's whales into the offshore seaThe main reason.

In order to protect the Bryde's whale, the Maritime Safety Bureau has allowed passing ships to change their course and excluded the protection of fishery administration vessels, so that Bryde's whales can hunt safely and safely. For two consecutive days of protection, it is obvious that the decision of the maritime department is very correct, and it does not make Bryde's whales feel frightened and threatened, and they hunt to their heart's content in the waters of Dapeng, Shenzhen. According to the staff of the maritime department, the Bryde's whale found this time has been exposed to the sea a total of 4 times in two days.

In addition, Bryde's whale is a first-class national key protected wild animal in China and an endangered species of the International Union for Conservation of NatureIt shows that Shenzhen has made great achievements in marine governance in recent years。It fully proves that China's marine pollution control and protection of wild fish stocks are in line with the law of natural development.

On the morning of July 3, the Daya Bay Maritime Safety Bureau issued an important notice to strengthen the control near the sea area where Bryde's whales are infested, and ask ships to maintain a safe speed when sailing through relevant waters, strengthen lookout, drive cautiously, do not watch, do not approach, and do not feed. It is recommended that all recreational vessels and yachts do not enter the whale activity waters without special circumstances to avoid adverse effects on whales.

Previously, a fisherman used a mobile phone to photograph a whale surfaced, the reporter asked Dr. Chen Mo, a well-known domestic cetacean research expert and associate researcher of the Guangxi Academy of Social Sciences, for verification, Chen Mo said after carefully reading it: "It should be a Bryde's whale." ”

According to the literature, this is the first time in 16 years that Bryde's whales have reappeared in the waters of Mirs Bay. Before the 80s of the last century, Mirs Bay and the adjacent Daya Bay waters were once a paradise for cetaceans and dolphins.

The ecological environment of the sea area has improved.

The appearance of Bryde's whales in the waters of Shenzhen said that the ecological environment of the Shenzhen waters has improved! Gradually move towards ecological environment optimization!

In fact, the Bryde's whale is not considered large in the cetaceans, generally about ten meters, and the blue whale is the largest in the cetaceans, according to the record of the two largest blue whales in length reached about meters and meters respectively, just the tongue can stand 50 people, the heart and the size of a small car, even the newborn blue whale cubs are heavier than an adult elephant, so far there is no greater cetacean than the blue whale, so, the Bryde's whale is much smaller than the blue whale.

According to research,The Bryde's whale does not move much on the surface but is an aggressive whale。The back of the Bryde's whale is dark gray, the ventral surface is yellowish-white, the average length is 12 meters, the female is 1 foot longer than the male, it has two stomata on the top of its head, there are three parallel protrusions between the stomata and the tip of the head, the fins are smaller than the other, the dorsal fin is protruding, sickle-shaped, there are two rows of baleen plates at the top of the lower jaw, and the number of Bryde's whales is about 300.

Because Bryde's whales are not very large, they generally use small fish as their main predatory pairElephantThe whales found in Weizhou Island in the North Sea are the first large cetacean living groups found near the coast in Chinese mainland so far, and have extremely important ecological scientific research value. Bryde's whales live in the waters near Weizhou Island, and in addition to feeding, they also shoulder the responsibility of breeding offspring

Bryde's whales are generally active at the surface of the waterIt is understood that around Weizhou Island and Xieyang Island, there are few coastal zone development activities, and the frequency of cargo cruise ships is less. Long-term regular appearance and feeding. Therefore, these conditions provide a favorable living environment for Bryde's whales.

The appearance of Bryde's whales indicates that the overall ecological environment and state of the Beibu Gulf are good.

Bryde's whales are larger, generally around twelve meters, and are one of the most mysterious whales.

The Bryde's whale is a whale that does not often float on the surface of the water, and it is also a predatory whale with some plankton attached to its body surface. There are no accurate research results on the details of their activities and mating habits.

Bryde's whales, which live in the deep sea or wider seas, are not killed by humans in order to adapt to the harsh living environment.

Bryde's whales should be larger than blue whales, and these whales should be very mysterious and few people can see them.

Bryde's whales usually live in the deep sea, which is mysterious and rarely seen. In terms of size, it should be a larger blue whale.

Of course, the blue whale is larger. Bryde's whales are mysterious because they are often active in the deep sea and rarely appear in people's field of vision.

I don't know, I haven't seen these two whales, but I heard that they are very large.

I think the blue whale is quite big, but the Bryde's whale has really not been seen, and I don't know very well, anyway, it is a very magical existence.

Bryde's cetaceans feed mainly on fish from oceanic clusters, such as sardines, eels, herrings, and mackerels. They also feed on small crustaceans such as krill and copepods, as well as cephalopods and oceanic red crabs.

Bryde's whales do not integrate into large groupsBryde's cetaceans in the North Pacific are usually alone or in groups of 2 or 3, with 12 being the largest group. Their jets are about 3 4m high. Usually after 4 to 5 breaths, do a long dive.

Sometimes you exhale underwater and then come out of the water, at which point there is almost no damp spray. They are rarely seen raising their tail lobes before diving. The usual swimming speed is about 2 7 km h, and when it is fast, it can reach 20 25 km h, and it can dive to a depth of 300 m.

The International Whaling Commission (IWC 1996) divided the Bryde's whale activity area in the North Pacific into three parts:The western North Pacific (west of 150°W, north of 2°S), the eastern tropical Pacific (east of 150°W, north of 10°S), the East China Sea, and the Gulf of California

The Southern Hemisphere is divided into: the western South Pacific (west of 150°W, excluding the waters of the Solomon Islands), the eastern South Pacific (east of 150°W, south of 10°S), the southern Indian Ocean, the northern Indian Ocean, the coast of South Africa, and the South Atlantic.

About 26,000 (CV=24%) in the western North Pacific (estimated based on survey data from 1998 to 2002).

About 13,000 (CV=20%) heads in the eastern tropical Pacific (Wade & Gerrodette 1993).

International Whaling Commission data for 1996: 137 in the East China Sea (not accounting for variance) and 235 in the Gulf of California.

Recently, on Weizhou Island in the Beihai Sea of Guangxi, Chen Mo, an associate researcher of the Guangxi Academy of Sciences, and his team were cruisingSuddenly, I encountered a Bryde's whale with its big mouth open and sticking out of the sea to hunt and pass by the scientific research ship.

According to the newly released List of National Key Protected Wild Animals, Bryde's whales are listed as national first-class key protected wild animals.
