Why are whale watching boats still a potential threat to bigfin whales?

Whaling is hugely controversial, and as calls for wildlife protection have grown, whales have shifted from canned food in supermarkets to whale watching to the general public, and the opportunities to swim with whales have gradually increased.

After nearly a month of training, I officially started working as a whale watching guide, and from December to the end of March, I saw all the inshore behavior of the greatfin whale during the day in the breeding waters of Okinawa Zamami. Whale watching boats remain a potential threat to bigfin whales.

Although not as life-threatening as large ocean-going transport vessels can cause migratory whales, the noise of whale watching boat engines and the excessive concentration of whale watching boats are undoubtedly stressful for the breeding season for greatfin whales. At the beginning of the whale watching season in December and at the end of the whale watching season in late March, due to the small number of large finned whales, several whale watching boats usually go whale watching around a single large fin whale.

However, for ordinary people who step on a whale watching boat and ask "what are big-fin whales" and "how big are they", rather than telling them on a whale watching boat that "adult bigfin whales are about the same size as our whale watching boat, and they come to Okinawa from the Siberian Sea to court and breed", do they want them to buy a can of canned whale meat at the supermarket and exclaim, "It's a bit like canned beef, but it's still delicious"?

Fortunately, with the development of the whale watching industry, whaling along the coast has been banned and whale watching has gradually become regulated: in various whale watching areas in Japan, whale watching associations have issued regulations to limit the distance between whale watching boats and whales, and limit the time of tailing. The overall number of bigfin whales observed off the coast of Japan has also steadily recovered.

But is what we know about the creatures of the ocean, and enough for the public to pay attention to the giant creatures of the sea, far from the everyday creatures? Are there still some people who still worry about "what can be done" after seeing these magnificent and beautiful creatures with their own eyes?

The noise of the engines of the whale watching boats, and the accumulation of too many whale watching boats, are an invisible pressure on the bigfin whales during the breeding season.

I guess I'm afraid that humans will hunt it down and pose a threat.

This will affect its activity or predation.

Because for whales, they are afraid of humans.

Whale watching boats are still prone to sound disturbance and are a threat to whales.

Whales are afraid of humans, and whale watching boats can have a big impact on whales.

They are still afraid of humans and are afraid of eating and affecting their living environment.

Pollution of the biological environment, the impact of sound waves on life.

Whale watching boats cannot be ruled out as hunting.

Even if the person is not intended, the oars are still potentially dangerous.

Bigfin whales will think that the boat is here to catch them, and think that they are enemies.

I feel that the unknown is dangerous.

The whales are first driven away, then caught with nets and then placed in tanks and transported to the oceanarium.

Fishing boats are used to drop bombs under water, and whales are driven to a certain place to catch them. The people caught the whale in the ship's trapped hail and transported it to the water tank Wang Fan.

The way to catch dolphins in the wild is simple and crude, and it is easy to understand. Boats and small aircraft use a series of underwater bombs (sealbombs) to make a loud noise under the surface of the sea, driving the pods of wild dolphins (pods) offshore to the bay, and then sealing the bay exit with nets, and the pods are transported into turtles in urns.

Whales leap out of the water to increase the socialization between whales and enhance friendship with each other. You can also show off your strong body by jumping out of the water to show off your strong body and gain the favor of female whales. Or maybe it's just for fun.

Our nature is very wonderful, there are many kinds of creatures in nature, and these creatures complement each other and are indispensable. Whether it is from a relatively small ant to a relatively large elephant, they all have their meaning. Today I want to talk about one of the larger creatures in nature, which is the whale.

Whales live in the sea, their size is very huge, some weigh dozens of tons, so that we human weight is many times the weight of human beings, we humans in front of whales, is a very small existence.

We often see whales or schools of whales on TV, jumping out of the water in groups. It is thought that whales are relatively large in size and generally feed on small fish and shrimp in the ocean. A few tons of food go into the mouth at any time, so hunting is very energy-saving, after all, whales are relatively large and cannot move as agile like other fish.

Therefore, it is very physically demanding for whales to jump out of the water, and the reason why they do this is because they also need a certain amount of socialization.

Some people believe that whales need a certain amount of flapping force and elasticity when jumping out of the water, and because of the body comparison, the sound they make when entering the water is also relatively large. Especially during the mating season, many whales jump out of the water in pairs, and the sight is very spectacular. Doing so will better attract females, show off their size and strength, and increase the chances of a mate.

Others believe that whales jump out of the water purely because they are happy, or because they are playing to enhance the relationship between whales. It's like when we humans are happy, we jump up and cheer.

There are several different theories about whales jumping out of the water: one is that whales jump out of the water significantly more often during the courtship period to show their strength; There is also a theory that it is an act of keeping order in order for the fish to smoothly separate or converge; The last theory is that it is purely a form of amusement for whales.

Jumping out of the water is a social action of whales, and when a whale jumps out of the water, nearby whales will do the same, using this movement to form bonds, and there are also studies on surfaces that may be due to courtship or fighting.

Their goal is to show their strength to their significant other, to impress their partner, and to make more friends for themselves.

Why do whales jump to the surface.

Whales are divided into two categories, one is baleen whales and the other is toothed whales.

Whales theoretically have no natural predators.

Whales belong to the phylum Chordates, subphylum vertebrates, mammals, and eumatria, which contain about 98 species of viviparous mammals living in oceans and rivers. There are more than 30 species in China's waters. All species of whales inhabit the ocean, with the exception of a few that live in freshwater.

The definition of the whale itself is vague, and the whale can encompass all cetaceans, as well as specific families of cetaceans. All dolphins are also included in the whales. There are two main species of whales: baleen whales (mysticeti) and toothed whales (odontoceti).

Baleen whales are small but huge, with the smallest known species being over 6 meters long, and the largest animal, the blue whale, is also a baleen whale. However, the size of toothed cetaceans varies greatly, with the smallest species only about 30 cm in length and the largest sperm whale more than 20 meters long. Whales do not belong to the class of fish, but to the class of mammals.

General introduction to whales:

Whales are giant creatures in the ocean, mammals in the same orbit as dolphins, (but larger in size than dolphins, with a shorter muzzle, evolved forelimbs in the shape of flat fins, vestigial hind limbs, shell fins, a broad, flat tail, and a stomat.) Upper cetaceans (suborder and baleen whale and extinct ancient cetagna) – Baleen whales and extinct ancient cetaceans, and cetaceans that cannot be classified in the family Dolphins.

It is widely distributed, and its traces can be seen in the sea areas of the world, which is oceanic, and the behavior takes more group activities, and rarely acts alone. Like dolphins, they like to have fun when foraging, such as jumping and hitting the waves, whale tail lifting, whale tail hitting the waves, and snorkeling.

Types of whales: There are about 12 species of whales that inhabit the Southern Ocean: baleen cetaceans and toothed cetaceans. Larger baleen whales include blue whales, finwhales, blackboard baleen whales, bridle whales, gibbon whales, and right whales. Larger toothed whales include sperm whales and orcas, among others.

The largest of these is the blue whale and the most numerous are the finwhales. Gibbon whales and right whales are now almost wiped out, with few survivors.

Whales are widely distributed in the Southern Ocean, and they can be found almost south of the Antarctic convergence zone. Their distribution is closely related to the distribution of krill colonies. Blue whales are mainly distributed in the ice floe zone, and the southernmost ones are gibbon whales and blackboard baleen whales, the gilbby whale can winter in Antarctic waters, and the right whale is mainly distributed in the subantarctic region; Toothed cetaceans are found in the Antarctic convergence zone and migrate with the seasons.

Whale Habits:

Fin whales are accustomed to living alone, and in the same sea area, males and females coexist. Male fin whales can also use their "songs" to attract female fin whales hundreds of kilometers away to their well-fed breeding grounds to mate with male fin whales. Because the whale's "song" frequency is similar to that of some military or commercial sonars, sonar is likely to interfere with fin whale reproduction, making the already low reproduction rate of this species even more difficult.

The horned whale, with a white belly and a black back mixed with blue-gray or black-gray spotted patterns, has a horn about 1 2 meters long on its head, which is actually teeth, and most people currently believe that the horned whale's tusks are just a sign of secondary sexual characteristics, which resembles the mane on the head of a male lion on land. (Habits to be examined).

Whales were originally thought to be animals that walked on all fours on land, but later "went to the sea" due to foraging problems, and practiced monogamy, like "bigfin whales" usually live alone, while other whales also live in groups. Their gestation period is generally about 12 months, one litter and one son, and the lactation period of young whales is 10 months, and the lifespan is about 60 to 70 years.

Whales migrate in certain waters in the cold zone and warm generation, and have a fixed return route. In the summer, they live in the cold zone and replenish their nutrients, and in the fall, they begin to move to the warm sea for breeding.

Note: Killer whales eat a lot of food, and there have been records of one killer whale eating 13 dolphins and 15 seals. ）

To be precise, whales have no natural predators.

The information is very complete. The natural predator is humans.

The lifespan of whales reaches several decades to a hundred years.

1.First of all, the animal world is the same as the human world, each creature has a certain living space and food, and there are certain natural enemies, and there will definitely be a war between each other.

2.We don't want to intervene too much in such a war, although in our subjective emotions we must sympathize with the weak and belittle the strong, but we have to use human behavior to intervene in the laws of nature, which will inevitably lead nature into a dead cycle, causing a wide range of biological death and biological faults.

3.We must protect the animals, but we must not interfere with nature, because every creature has its own trajectory.

The school of fish will not have any effect on the aircraft carrier, first of all, there is no school of fish that has such power.

As for whales, the largest is a blue whale with a length of 30 meters and a weight of 180 tons, and the smallest aircraft carrier is close to 200 meters with a displacement of more than 11,000 tons.

Blue whales can swim at a maximum speed of 50 kilometers per hour, about 26 knots, and if the aircraft carrier is at its top speed, they will not even be able to catch up.

There is also the fact that the propellers of large ships can roll up a lot of splashes and bubbles under the water, and there will be cavities, and fish will be sucked into the vicinity if they get close. As a result, fish are usually found around or next to the boat, but not too close to larger vessels.
