Killer whales are large marine mammals with the following physical characteristics:1The body is massive, with a body length of up to 9-10 meters and a weight of up to 6-8 tons.
2.The head is large and rounded, the muzzle and nose protrude forward, and the mouth is medium in size. 3.
The body is grayish-black or black, with spots, stripes and other patterns on the surface. 4.The dorsal fin is tall and curved on the posterior edge and darker in color.
5.The caudal fin is broad and thick, and the trailing margin is wavy. 6.
The lateral fins are short and triangular in shape. 7.The large eyes and high position make it easy to observe the surrounding conditions on the water.
8.The teeth are sharp, up to about 15 centimeters, and are used to hunt seals and other marine life. Overall, killer whales have unique physical features that are easily recognizable.

1. Each killer whale group has its own communication system.
Killer whales have a complex communication system that includes a wide variety of voices, including singing and whistling. Since the members of the same group spend a lot of time together, they begin to build their own voices** to identify them, and this is something that the other members can't understand.
2. Killer whales will go through menopause.
There aren't many menopausal mammals, but killer whales are one of them. Females lose their ability to reproduce at a certain age but live longer.
3. The lifespan in the natural habitat is longer than that in captivity.
Although scientists don't agree on how long the Great Oak Killer Whale can live in its natural habitat, in captivity, killer whales live no more than 20 years.
4. There is a unique mark on the dorsal fin.
This area works in a similar way to our fingerprints. Therefore, each killer whale can be clearly distinguished by this, which is useful for scientists to identify them.

The black baby whale (orcinusorca) is a large toothed whale with a body length of 8-10 meters, a weight of about 9 tons, a slightly rounded head and an inconspicuous beak. The dorsal fin is tall and erect, bent up to 1 m; The body is black and white.
The wings are far apart.
The temporal fossa is large. The mandible is comparatively shorter.
The upper and lower jaws have 10-12 conical teeth.
With a slender mouth, sharp teeth, and a fierce temperament, it is a carnivore, good at attacking prey, and is a natural enemy of penguins, dolphins, seals, and other animals.
Sometimes they attack other whales and even great white sharks, which can be called the supremacy of the sea.
The black cub whale is a highly social animal, and some group families are the most stable in the animal kingdom.
Some of the killer whales' complex social behaviors, hunting techniques, and voice communication are considered evidence that killer whales have their own culture.
It is found in almost all ocean areas, from the equator to the polar waters.
Or the depth of the water temperature does not limit its range.
Extends to many enclosed or semi-enclosed seas, such as the Gulf of Alaska, the Mediterranean, the Sea of Okhotsk, the Gulf of California, the Gulf of Mexico, the Red Sea, and the Persian Gulf.

Many people call us whales, but in fact, we whales are mammals. Once upon a time, our cetacean ancestors, like other mammals, lived on a vast land. However, due to changes in the environment, we had to leave our homeland and come to the beach to survive.
After many more years, the forelimbs and tails of our ancestors gradually became ji, and the hind limbs completely degenerated, gradually adapting to the marine environment. In addition, many physiological characteristics such as lung respiration and viviparity also prove that we are mammals. There are more than 80 species of whales, and you humans have classified us, and there are two divisions, the first one divides us into baleen whales and toothed whales, and here, we killer whales belong to the second species; The second type divides us into half-open whales, eight-open whales, and twelve-open whales, and we killer whales still belong to the second type.
For the sake of time, I will only introduce the first division today. As is customary, let's start with baleen whales! Baleen whales are big guys like blue whales, sperm whales, etc., they have no teeth, only whiskers, no resistance, can only live by eating small fish and shrimp.
And our toothed whales are different, all of our toothed whales are martial arts masters in the ocean, and our killer whales have reached the point of seeking defeat alone, and our sharp teeth are our unique weapons. When we swim in the ocean, all the animals stay away, and once we find it, then you should make a will. You might say:
You can't eat big guys like blue whales and sperm whales? "Actually, those guys have almost no other advantages except for their strength, so of course, they have become our meal, and some people say that we are cruel, in fact, if we hadn't eaten those old and weak whales, perhaps, our whale family would have been in a mess.
However, we toothed whales, especially our killer whales, are too good for you humans, we never hurt you and do a lot for you. Once, a colleague of mine wrote to me that he had finally become the captain of a ship. In fact, almost every killer whale has experienced this position.
This is the duty of putting one or two people on our backs, and we carry the tourists around the sea according to the instructions of the animal trainers. However, you humans also bring us comfort. You've worked hard to develop our potential and taught us what it means to have two or more movements and fuzzy movements that gorillas don't understand.
In addition, a British ** enthusiast also planned a "concert" for us! Okay, that's all for today, goodbye.

Characteristics of bees: bees are insects that feed entirely on flowers (including pollen and nectar), when the external nectar source is abundant, the bee colony will collect the nectar to make honey and store it in the hive, these stored honey is actually the food stored by the bee colony for emergencies, for example, the bee colony can not go out of the nest to collect food in winter to feed on the stored honey, and in beekeeping production, beekeepers also often use sugar and soybean powder as feed to feed bees. Habits of bees: >>>More
