Usually speaking of animals that can live on land and do not need to rely on water, the first thing that comes to mind is the African lungfish, which is a very peculiar existence, as soon as it rains, they jump out of the cracks in the wall, and they are still alive, at which time the African people will take the opportunity to start grabbing it and making a delicacy to replenish their physical strength. But in addition to lungfish, there are also such strange fish in the world, including a fish that can walk on land, not only can run and jump, but also the ancestor of amphibians!
Can you guess what kind of fish it is? I believe you must not have seen it, that is, mudskipper, is it already a little strange to you after saying its name?
In fact, there is a second name for mudskippers, which everyone knows, that is, it is called jumping fish, they are marine fish, and they belong to the mudskipper family. Their bodies are short and long, with short mudskippers about 70 mm long and tall mudskippers growing even 180 mm in size. In addition, their heads are very large, but their bodies are a little flattened, the whole is light brown, and there are many dark dots scattered on the side of the body, and more interestingly, their eyes are like two small protruding bubbles, growing on the top of the head.
However, their biggest feature is that they have two muscle stalks on the back of the body, a bit like the forelimbs of land animals, and mudskippers can use it to swim, support the body, and even rely on it to go to land.
Mudskippers prefer to live in warmer waters, so they often inhabit the semi-salty waters of mangrove forests, and the river bottom is mainly sediment. Therefore, mudskippers are mainly distributed in coastal areas or near some islands.
Mudskippers are actually very fond of land, they will use their muscle handles to crawl on the beach or rocks after low tide, compared to crawling, in fact, they are better at beating, just like their name, but usually almost all nestled on the beach to enjoy life. Their hearing and vision are very sensitive, and once they perceive that a living person is approaching, they will quickly jump into the water so that others cannot catch them.
The most amazing thing is that its skin can breathe, whether it is underwater or on land for a long time, it is very adaptable to the environment.
They evolved from ancient fish and are the ancestors of amphibians. Because the transition from aquatic to terrestrial is the most important event in the evolutionary history of vertebrates, many amphibians have evolved pectoral fins and limbs for walking in the process of adapting to terrestrial life.
But such a shift is actually related to their genes, and seeing these animals reminds us of the first vertebrates that landed on the continent 360 million years ago. Although from an evolutionary point of view, mudskippers are not related to ancient fish chances, but they are also the result of their evolution, and they still retain the characteristics of the original fish, so we say that they are the ancestors of amphibians.
According to scientific studies, mudskippers have different genes from other amphibians, and this gene appears in the process of their evolution, which makes them different.
However, what is surprising is that although this mudskipper is known as the ancestor of amphibians, it has long become a food on the table, because of their strong survival ability, and high reproductive ability, more importantly, their flesh is delicate and tender, is a high-protein, low-fat, high-vitamin food.
As a delicacy, mudskipper fish can also be used to treat diseases, mainly for those with infectious hepatitis and diarrhea. Putting aside the medicinal value, mudskipper is also very suitable for the elderly to eat, because the fat content is small, and there is a cardiovascular protection substance, which is an ideal food to prevent some diseases of the elderly.
Therefore, the mudskipper is not only very distinctive in itself, but also a delicacy on the table, you can buy it back and give it to the elderly at home, oh, this is a very good gift!
