Which animals can stick out their tongues to dissipate heat like dogs?

Recently, the continuous high temperature in Hangzhou has made African lions in zoos stick out their tongues like dogs to dissipate heat. In fact, apart from dogs and lions, we often see some animals sticking out their tongues to dissipate heat, especially when the weather is hot. Let's discuss with you which animals stick out their tongues to dissipate heat.

First of all, let's talk about the reason why animals spit out their tongues to dissipate heat. According to scientific research, it is because the position of the tongue can help animals dissipate heat when their blood circulation is fast, which is one of their natural ways to adapt to the weather changes.

Most of these animals are relatively standing, that is, their weight is concentrated in the lower part of their bodies, the upper part is relatively light and the lower part is relatively heavy. When they stand in hot weather, their upper body leans forward and their lower body leans backward. This will change their center of gravity, leading to instability and the risk of falling.

To avoid this, they stick out their tongues as "protection". When they stick out their tongues to dissipate heat, the blood on their tongues will circulate to the neck and head, so that the whole body will get accelerated heat dissipation. In this way, you won't fall so easily.

In addition, because there are a large number of blood vessels and neurons on the tongue, it will react when stimulated by hot weather. These reactions will reach the brain through neural pathways, telling the brain that "the weather is very hot". The brain will then take corresponding actions to help animals tide over the difficulties, that is, order animals to stick out their tongues to dissipate heat.

Animals that spit out their tongues to dissipate heat mainly include:

1. Dog

Dogs are the most common animals that we see to cool down by sticking out their tongues. Dogs are mainly because most sweat glands are underdeveloped and covered with hair, so when the weather is very hot, the body's protection mechanism will tell dogs to spit out their tongues to dissipate heat, so as to avoid heatstroke or even shock death due to overheating.

2. Cats

Cats are a large population. In addition to the cute kittens we saw, there are African lions, leopards and other big cats. Cats also have sweat glands, but they are far from the developed level of human sweat glands, mainly concentrated in places such as foot pads, so they should spit out their tongues to dissipate heat in hot and high temperatures.

3.giraffe

Giraffe, as the highest temperature mammal, has a normal body temperature of 40 degrees. In order to maintain normal body temperature, they have to use their tongues to dissipate heat, which is also a way for giraffes to protect themselves. Although in most cases, giraffes stick out their tongues mainly to eat and protect organs such as the mouth, heat dissipation is also something they have to do.

These are the animals that can spit out their tongues to dissipate heat like dogs. Either way, it is the result of long-term survival and evolution. Protect yourself.
