The dolphins are known as “the strongest curable animals on the surface” because of their character, their friendship with other animals and their stupid appearance. Recently, however, it has been reported by foreign sources that Nodelta, Argentina ' s first rich area in the north, has been “invaded” by the world ' s largest rodent dolphins, who have vandalized the lawn of the inhabitants, vandalized their living environment in random sizes, caused frequent traffic accidents and even attacked their pet dogs. Why, then, do the curable animals become so "grumpy"? Let's talk about this.

Let's get a quick look at the dolphins.
Dolphins are rodents, and when it comes to rodents, many think of rats first, but dolphins and rats are just the same rodents, and they are beginning to divide from science, and their differences are like cats and dogs. The dolphins were first divided into dolphins, but a 2002 study of molecular systems showed that the dolphins had a recent relationship with the rock porpoises, so the dolphins, together with their “neighbors” porpoises (the largest difference being the number of chromosomes, of which the porpoises were 52 and the porpoises 51), were divided under the porpoises, although it was single-like with the porpoises.
The dolphins are a rodent of origin in South America, and they are widely distributed in South America, and they are visible in jungles and grasslands, almost all except Chile. Moreover, dolphins are the largest rodents available, with an average of 1.2 metres in length, 55 centimetres in shoulder height (over half a metre) and 45 kilograms in weight, which is even higher than the average medium-sized dog. This is not yet the largest dolphin, and the largest dolphin in the wild is currently recorded to weigh as much as 91 kg, which is more than a half head of fat.
Although the dolphin is fat, it is a pure herbivores. As a semi-aquatic animal, the dolphins live in two factors: water and grass. As a rule, dolphins are kept in water in the middle of the sun, and only before sunrise and before sunset are they able to reach the shore for food. As a rodent, dolphins also have growing mouths, although they have larger characteristics of chewing food (the dolphin ' s jaws are not moving, resulting in it chewing food back and forth) and feeding (who eat 3 kg of plants a day), keeping their mouths under a relatively stable length.
In addition, since dolphins can only chew food back and forth, which is also a coarse-fibre plant, many foods in the digestive system are difficult to digest, and they bring out bacteria in the intestinal tract, so the dolphins have the habit of eating their own faeces (hot to eat because they contain large intestinal strains).
The dolphin is a herbivorous animal, combined with its obese shape, so in South America it is the target of many predators, such as the largest cats of the Americas, panthers, and the world's largest snake-simmons.
Despite the fact that the dolphins appear to be fat and have shorter legs, they run on land at a speed comparable to that of horses, which can run up to 50 kilometres per hour in the event of a natural enemy. This is the most powerful weapon a dolphin can escape from a natural enemy.
In terms of character, the dolphins are relatively gentle and have little territorial awareness, are usually very friendly to other animals and therefore interact closely with people in many zoos, and, as pets, they are kept in some countries. Here's a set of maps to find out what a dolphin looks like.
How can such a cute and friendly dolphin become an animal with a headache?
Although the word “invasion” has been used in the report, I think it is inappropriate because Argentina is already one of the distribution areas of the wild species of dolphins. It is true, however, that there has been no “location” of dolphins on such a scale before. So, what caused this?
Number one: the reason for the proliferation of dolphins. The first proliferation of dolphins in the north of Argentina has two main causes: the reduction of natural enemies and the capacity to reproduce. As we said above, the main predators of the dolphins are leopards, crocodiles and senora, but with environmental damage and man-made hunting, the number of these predators is decreasing, which leads to a decline in the number of predators. Added to that, a female dolphin can produce two to eight cubs a year, so they can spread rapidly where there are real predators.
Second: the reason for the dolphin “invasion” of the rich. Nodelta is the first region in Argentina in the northern part of Buenos Aires, for a reason, because it is one of the most suitable areas in the subtropical monsoon climate, with clear seasons and abundant rainfall. But this is the “home of the dolphins” until the rich have been built. When humans arrived, these animals, friendly to other animals, were not moved by humans, but were all lost. So, their numbers expand rapidly in a short time. However, an increase in the number of people who have been occupied by the rich has necessarily led to an “invasion” of human settlements. It would therefore be more appropriate to say that the dolphin “invasion” is rather a human “invasion”.
Third: Why would a gentle dolphin attack a pet dog? Dolphins are known in nature as “good tempers”, and they even allow a bunch of monkeys to play on their own. But what is the reason why, after entering Nordelta, the dolphins became aggressive by changing their warmth? The problem is the role of pet dogs, most of whom have the instinct to look after the home, and meet dolphins that are forced to evict in front of the meeting, but the dolphins are a group of animals, and they are no smaller in size than pet dogs, so the dolphins survive, the dogs look at the home, and conflict occurs. Although the dolphin is a herbivores, its teeth are powerful (refer to mouse bite marks, the dolphin's teeth are not rat teeth compared), and naturally the herds take over the wind in the face of pet dogs that have no field combat experience and have no carcasses.
Summary
This “invasion” of the porpoises in Argentina did cause the locals to suffer, but it was not so simple behind the “invasion” of the porpoises, because this rich area was once a porpoise's habitat, people came and other animals left, so that they did not go, so it led to an increase in the number, the number of people, the decline in habitat, and the inevitable entry into the neighbourhood, which was a chain reaction.
As for the lawn, they destroy the lawn because they are herbivores, and “go-and-go” is in itself the freedom of herbivorous animals, while pet dogs bite because pet dogs try to evict them and they defend their own space, that is all.
