What birds are big in the forest, but what about the sea? Today, Yi Ge introduced a few fish to everyone, and the magic of the fish in the vast and dark sea is not something we can think of.
Tube-eye fish with transparent head
Like a submersible
The tube-eye fish was discovered in 1939, and biologists now know that this eye is particularly capable of focusing light. However, their shape only gives the fish a tubular line of sight, so the field of view is very narrow. It has a transparent head and tubular eyes, figuratively known as the tube eye fish, and its tubular eyes can collect light from the deep sea, but the role of this eye structure has puzzled scientists.
How does it prey on survival in the deep-sea environment? The tube-eye fish is only a dozen centimeters long and feeds on small fish and jellyfish. The green in their eyes filters out sunlight from the surface of the ocean to the deep sea to help them spot glowing jellyfish and other animals overhead. When they spot prey, such as floating jellyfish, tube-eye fish roll their eyes, move forward and upward, and enter a predatory state.
A small prism in the water - a glass catfish
The name of the glass catfish comes from the two long, cat-like tentacles that are transparent throughout the body and grow in the mouth. They swim quickly, at an upward 40-degree angle when they stay still, and their crystal-like transparent bodies sway slightly, occasionally refracted by the right angle of light, they will reflect the rainbow-like dream colors produced by the refraction of sunlight by a triangular prism.
Glass catfish was originally scattered in Southeast Asia, Thailand, Malaysia and Indonesia and other countries, adult glass catfish body length can generally reach about 9-18cm, suitable for living in 20-25 ° C water temperature, glass catfish mild temperament, do not like to swim around, some timid, in fear will hide in the dim corner, is now one of people's favorite ornamental fish.
There are also fish in the water to the clear - bottle sea squirts
Previously, according to foreign media reports, a man caught a transparent fish, except for a small orange ball in the body, almost the whole body is transparent, you can clearly see the structure inside its body.
Transparent color in the water is the best protective color, if it is not hooked, the naked eye is basically unable to find. And it also has a clear fish scale pattern, which is also very tough to the touch, and looks like a fish.
Experts responded that it was supposed to be a bottle of sea squirt, a small distant sea gelatinous chordate that feeds on plankton in the sea. They can grow in groups and can last for months. Bottles are harmless to humans and generally live in cold seas to generate heat, but some experts have suspected that part of the cause of global warming may be caused by swarms of sea squirts.
Hours of transparent growing colorful multi-plate shieldtail fish
A transparent fish was found in the Mexican Sea. The fish was caught by Fishermen in the United States, who accidentally caught this strange fish as they prepared to catch tuna.
This fish is actually a juvenile fish of multi-plate shieldtail fish, which looks cute and cute when it is a child, and grows more colorful. And Yi Ge is very responsible for telling you this fish, you can eat.
Unknown pink transparent fish
Scientists have discovered a mysterious fish in the pitch-black waters beneath Antarctica's 740-meter-thick ice. They are pink in color, the body is transparent, and the internal organs are clearly visible. Because the waters where these fish live are only minus 2°C and are in permanent darkness, scientists have questioned the viability of fish that inhabit this extreme environment.
The top transparent fish – a plastic sheet that swims
This fish, even the internal organs are transparent. This is actually an almost completely transparent fish, or rather a special juvenile stage - a narrow-headed larvae. According to the Australian Museum website, the above swims like a transparent streamer may be the juvenile of the black-bodied tube-sniffed quaesita (Rhinomuraena quaesita, which belongs to the order Eel). Many moray eels and freshwater eels go through such a peculiar stage of growth.
The moray eels we often eat and the freshwater eels go through this stage of growth.
Transparent fish gives people a stunning feeling, but Yi Ge feels that there is also a little bit of bad, that is, you can't eat alone or steal food, and eat something that others can see at a glance. For example, the goods below, under the cute appearance, there is such a violent heart!
White-muscled silverfish
"My fish was lost, did you steal it?"
White Muscle Silverfish: "No! ”
"Talk nonsense with wide eyes!"
In fact, in addition to those special transparent fish, many fish, shrimp and crabs will show a transparent growth stage at a young age, on the one hand, the nascent cells are simple, and another important reason is that Yi Ge believes that it is also to avoid predators in order to improve the chance of survival.
