Grab DaHai You's tail.
In the lush underwater algae forest in the South China Sea, there is a rare small animal, which tightly wraps its curly tail around the stems and branches of algae. In appearance, it looks like a horse, with a protruding belly and a strange tail, as flexible as an elephant's nose. This is called seahorse, which is a kind of small fish in the ocean. Its swimming posture is very beautiful. When swimming in the water, it always raises its head, hangs its tail, stands up and makes vertical movements. It seems that athletes are racing! Because the hippocampus has no ventral fin and caudal fin, it can only rise and fall in the water by the swing of dorsal fin and pectoral fin, so its speed is much slower than that of ordinary fish. Hippocampus is naturally lazy. After swimming for a while, they will wrap their tails around the stems and branches of seaweed to have a rest, and then swim again. More interestingly, seahorses can also hang upside down on floating seaweed with hooked tails and roam in the sea!
You can't "fly" without a tail
In the fish show, the most attractive program is probably the flying show of flying fish.
Flying fish can "fly" on the sea because they have a pair of specially developed pectoral fins. But you know, it can't fly without the close cooperation of the tail. Please look at the take-off process of flying fish: when preparing for "take-off", it first puts its body close to the water surface, and then swings violently from side to side with its wide and hard tail, generating a powerful driving force to accelerate the fish's rapid progress until it rushes out of the water surface. Because pectoral fins are spread like wings, fish can "slide" freely on the sea. At the same time, the flying fish's tail can also control its direction. As long as the second half of the body is immersed in the water and tries to hit the water with its tail, it can change direction to the left or right.
A tail like a magic wand.
The long-tailed shark is a notorious "fish tiger" in the ocean. It is fierce and greedy, likes to eat all kinds of fish, and even attacks people who fall into the water. It has an amazing tail, about half its length, hence its name. It has a unique way of eating fish. When it found the fish, it first circled the fish like a "pull mill", then suddenly attacked, rushed into the fish, and attacked the east and west with its tail like a wand. After a bloody battle, it came back to enjoy this sumptuous "delicious meal" slowly. However, after all, the gastrointestinal volume is limited, and the stomach is full. On the sea where it passes, there are blood and residual fish everywhere. This is really an evil tail!
Tails can breathe.
There is an idiom in our country, which means it is futile to climb trees to find fish. This metaphor comes from the phrase "fish can't live without water", but they don't know that fish can really be found climbing trees in colorful nature.
The mudskipper living in the mangrove forest by the sea is such a fish. In order to find food, it often goes ashore in groups, leaving the water, grabbing the trunk with developed pectoral fins and climbing up unhurriedly. Crawling around the trunk, like a monkey in the forest, no wonder people nicknamed it "Zhou Yanyan".
How do mudskippers breathe on land after leaving water? After many studies by scientists, it is confirmed that there are many capillaries in its skin, which can directly exchange gas with the outside world; At the same time, its tail can also help breathing in the skin, so when you see a mudskipper at the seaside, most of its body is exposed to the water, and its tail remains in the water all the time. It is fresh air! More interestingly, when the mudskippers were suddenly frightened, they jumped into the caves on the beach, scraped hard on the picture with their broom-like tails, and even the muddy water swept into the caves. Blink of an eye, the painted surface becomes smooth and flat, leaving no trace and disappearing without a trace.
The tail was thrown half a day high.
Naked bonito is the "champion" of high jump in fish. It won this glorious title because of its powerful tail. The crescent-shaped tail bends easily and is as hard as iron. If you see a naked bonito still on the sea, just tap its tail with something, and it seems to wake up from sleep and throw it away at once. Like a rocket, the fish will suddenly jump 100 meters high. Look, what a great tail!
