It was very mischievous and mischievous, and it deliberately broke the castle that my brother and I had just piled up, and made my brother cry because he was so hard that he picked up the sand.

However, I didn't scold it, but just comforted my brother not to cry, I laid out the drawing paper and prepared to paint, and when I went to find a pen, it used its muddy feet when I went out to play to print a few flowers on the paper, "When I saw the painting paper, I guessed that this must have been done by Taotao."

However, I didn't re-draw "but added some branches to the painting" plus a few leaves, which also has the credit of Taotao, it is very playful, and people are particularly worried! It wouldn't come back, and it took me a lot of effort to find it.

The puppy's head resembles a fluffy furball.

Its shape is about the same size as three laptops stacked on top of each other, and it roars as soon as it is opened, and when you put your hand on the heat vent, it feels like you are blowing air conditioning heater. It's such a cold day, so I have the urge to take my socks to the classroom and put them on top to dry... This is the projector we are retiring.

Little Rooster: I love my little rooster that sows. It has a crown like a torch on its head. The feathers on his back seem to be wearing a crimson shiny tunic coat.

The feathers on the belly resemble a blouse. A pair of translucent and flexible eyes and a pointed mouth, coupled with the most striking colorful tail, look beautiful and mighty.

The little rooster stands on the platform in the morning and crows vigorously, urging people to get up quickly.

Usually, the little rooster is still an expert at catching insects! Although some of the bugs are very alert, as long as they move, they can't escape the eyes of the little rooster. Once, I saw a little bug crawling out of the grass under a tree for a walk, and the little rooster spotted it.

I saw that the little rooster ran quickly under the tree, and with its sharp and slender mouth, it caught the little insects at once, and in this way, all the little insects became a delicious meal for the little rooster.

"Dog" dog, also known as "dog" in Chinese, belongs to the carnivorous order and is distributed all over the world. Dogs, horses, cows, sheep, pigs, and chickens are called the "six animals".

Some scientists believe that dogs were domesticated from gray wolves by early humans, and the domestication time was 40,000 years ago 150,000 years ago, and it has developed to this day. Known as "man's most loyal friend", it is now the most popular pet. Its lifespan is about more than ten years.

In canines, such as dogs and wolves, the sweat glands in the body are not very developed. They can't regulate their body temperature by sweating like humans, and it is difficult for them to lower their body temperature once it heats up, so dogs are very afraid of heat.

Dogs also have two types of sweat glands, exocrine sweat glands and apocrine sweat glands. The exocrine sweat glands used to regulate body temperature are only distributed on the flesh pads of the four paws, and there are very few of them, and it is impossible to lower the body temperature by sweating a little from the paws. The apocrine sweat glands that cause their body odor are distributed throughout their bodies and have nothing to do with thermoregulation.

As soon as a dog feels a little hot, it will open its mouth, stick out its tongue, and gasp for air, which in doing so can secrete a large amount of saliva instead of sweat. Dogs dissipate heat by vaporizing their saliva, lowering their body temperature. They drool profusely and lower their body temperature by evaporating saliva and absorbing heat.

When it's hot, this method alone won't be able to cool you down. Therefore, it is difficult for dogs to lower their body temperature. In particular, dogs with very small heads, such as pugs, horn dogs, poodles, and Chihuahuas, are not good at regulating their body temperature because of their short respiratory organs, and are particularly sensitive to heat, so they should pay more attention.

In our culture, the dog belongs to one of the 12 zodiac signs and ranks 11th among the 12 zodiac signs.

Fishes are the oldest vertebrates, they have been around for more than 100 million years, and they are also the largest group of vertebrates, with more than 10,000 species. Fish have some common characteristics, that is, the vast majority of fish inhabit the water, use gills to breathe, the body is covered with a layer of scales, swim with fins, and have swim bladders in the body. When we look at a fish, we will find that the fish's mouth is constantly opening and closing, in fact, it is the fish breathing.

The gill cover is covered when the fish absorbs water to prevent the loss of inhaled water; Then, the mouth of the fish closes, and the pressure of the inhaled water is discharged to the gill cover, and at the same time, it is transmitted through the gill filter to the whole body, and then the mouth of the fish is opened, and the breath is burned for a round of breathing. Just as fish vary greatly from one fish to another, different fish have scales of different shapes. However, not all fish are scaly, they are replaced by a particularly rough shell, such as a seahorse.

The fish can move forward or stand still in the water, which depends entirely on the oscillation of the fins. Swing the tail fin to create thrust, and the fish will move forward; The pectoral and pelvic fins are used to allow the fish to change direction accurately and to rest quickly. The shape of the fins reflects the habits of the fish.

pelagic fishes that advance extremely fast, their fins are slender and narrow like blades, and their tail fin has a deep fork; Fish that advance slowly and are good at controlling their direction have wide fins and a flat and square tail fin.
