According to foreign media reports, subtle physiological adaptability makes all kinds of animals as transparent as water through evolution. Like mimicry animals imitating the environment, transparent animals take a more extreme approach, that is, they become transparent and disappear completely to avoid enemy attacks. Want to know which cute animals are so smart to protect themselves? Let's take a look at these top ten transparent animal wonders.
1. The internal organs of transparent frogs are clearly visible.
Glass frog (glass frog)
Glass frogs, native to Venezuela, belongs to the amphibian Ranidae (also known as the green bone Ranidae). Although glass frogs's back is gray-green, some members' abdominal skin is translucent. Through translucent skin, we can clearly see its heart, liver and digestive tract. They live in tropical rain forests, along streams and on foggy mountains. At present, about 138 species of glass frogs live in central rainforests and South America. Adults in glass frogs live in trees, which are green and in harmony with the surrounding green leaves. Some species lay eggs on leaves above streams. After the eggs hatch, tadpoles will fall into the water below until they grow limbs in the water and then jump back to the tree. There is a tadpole in glass frogs that is bright red. They buried themselves in underwater soil and rotten leaves. Amphibians, such as glass frogs, are regarded as indicator species, and their numbers reflect the overall environmental conditions. Now, many glass frogs species have been listed on the IUCN Red List of Endangered Species because logging and farmland reclamation have destroyed their rainforest habitats.
2. Transparent fish has a transparent head.
Macroptera microphylla
American biologists found a strange fish in the deep sea. It has a transparent head and tubular eyes. It is vividly called the tube-eye fish, and its scientific name is Macropinna microstoma. Since this kind of fish was discovered in 1939, biologists now know that this kind of eye can concentrate light especially. However, their shapes only allow fish to have a tubular line of sight, so the field of vision is very narrow. Scientists say that this kind of eye can rotate, so that the tube-eyed fish can look straight ahead or look up through the head, searching for the faint outline of the prey's head, which is very suitable for survival in the dark deep sea environment.
However, scientists used to think that this eye could only concentrate steadily upward, so that the fish could not look forward, so it was difficult to catch small prey. Now, Bruce of Monterey Bay Water Cluster Institute in California, USA? Robinson and Kyoto Electronics Industry Co., Ltd.? Allison Bichler filmed a video with a remote control device, and studied the tube-eyed fish in the waters of central California in detail. They found that in the sea water of 600-800 meters deep, the video taken by the remote control device showed that these fish had been floating in the water, and their eyes were bright green under the strong light of the remote control device. This video also reveals a detail of these fish that we didn't know before: we found that their eyes were protected by a transparent shield, which was filled with liquid and even covered their entire heads.
Most of the existing descriptions and illustrations of this fish do not show this liquid shield, probably because this fragile structure is easily destroyed when this fish is fished out of the deep sea by fishing nets. Fortunately, the tube-eyed fish caught in the fishing net salvaged by Robinson and Kyoto Electronics Industry Co., Ltd. of Japan is still jumping around when it comes out of the water, which proves that the fish can turn its eyes when its posture changes from horizontal to vertical.
This tube-eyed fish is only a dozen centimeters long and feeds on small fish and jellyfish. The green color in their eyes can filter sunlight from the ocean surface to the deep sea and help them find bioluminescent jellyfish and other animals overhead. When they find floating jellyfish and other prey, the tube-eyed fish will turn their eyes and swim forward and upward to enter the hunting state.
3. Transparent butterflies have transparent wings.
Glass wing
As the name implies, the butterfly (Glasswing) in Central America, Mexico and Panama has a transparent tissue between its veins, which looks like glass, so you can see what is behind its wings through its wings. There are no colors and patches on the wing membrane. Did the creator give it? Invisible? Can it be easy? Disappear? In the forest, it is not easy to detect its existence. But it is not the only butterfly with transparent wings. In the same family, there are several other butterflies, which also have transparent wings.
Although the transparent butterfly is strange to people, it is actually not listed as a rare species because of its large number in its place of origin. The yellow and black stripes on the butterfly make it look like a wasp; It is not easy to be found and captured by the enemy, which is the behavior of living things to adapt to the environment in order to survive. Chiroptera can't be eaten, which makes birds attack it less and is beneficial to its survival.
4.transparent squid
Glass squid
What is the scientific name of the glass squid found in the deep sea of the southern hemisphere? Stripe worm? It belongs to the family Sparidae and generally lives in the middle and upper ocean. It has shiny organs in its eyes, and its body is transparent and very soft, and it can curl up like a hedgehog. Most of the time, they live near shallow seas and use transparent bodies as protective colors, but they are often eaten by sharks or seabirds in the sea.
5. Artificial culture of transparent zebrafish
zebra fish
The zebra fish in the picture is a fully transparent zebra fish successfully cultivated by scientists in 2008. People can directly see various organs in zebrafish, and even observe the growth process of cancer cells in zebrafish in time to study the diffusion mechanism of cancer. This fish is being used as a living body by scientists to observe the spread of tumors in real time at Boston Children's Hospital. Scientists bred this transparent zebra fish by pairing two existing zebrafish, and gave it a nickname? Caspar? . Among these two kinds of zebrafish, one is lack of reflective skin pigment, and the other is lack of melanin in the body. Their offspring only have yellow skin pigment and look transparent. Zebrafish, a common tropical fish, is a genus of Cyprinidae, native to South Asia. Zebrafish gene has many similarities with human beings, so it is an excellent model for scientists to study human biology and diseases. At present, zebrafish has been widely used in developmental biology, genetics, oncology, pharmacology, toxicology and environmental protection, and some new research results have been discovered.
6, transparent ice fish
Crocodile ice fish
Ice fish growing in cold regions such as Antarctica and South America are also called crocodile ice fish, because their snouts are shaped like crocodiles, and they are also called white blood fish because they lack red blood cells and heme. The blood of alligator ice fish is transparent because there is no hemoglobin or bioactive red blood cells in the blood. Its blood carries much less oxygen than fish with red blood cells, but its heart and branchial blood vessels are larger and its circulating blood volume is larger, so it can absorb enough oxygen from the oxygen-rich Antarctic seawater, which scientists believe is obtained directly from the water flowing through the skin. Generally speaking, the lower the temperature, the greater the dissolved oxygen in water, which also provides the possibility for it to evolve such a special metabolic model. There are about 16 species of crocodile ice fish, most of which are distributed in the Antarctic and mainly feed on crustaceans and small fish.
7. Transparent platypus
Fronima
During the expedition to the deep-sea mountains in the North Atlantic, scientists discovered many unusual creatures, among which Fronima was one. This little shrimp-like creature is transparent and can see through from the inside out. They try to disguise themselves better in the dark environment and escape the eyes of predators in this way. Many other types of deep-sea creatures also adopt this strategy.
8, transparent shrimp
Transparent shrimp
This transparent young shrimp was found in the sea near Hawaii. It is riding on the back of an equally transparent jellyfish.
9, transparent bottle sea squirt
sea squirt
This jellyfish-like animal, called Salp, feeds on phytoplankton (algae, etc.). ) and move in the water by inhaling and spraying seawater. Their bodies are barrel-shaped transparent tubular animals, with the length ranging from 1 cm to 10 cm.
10, transparent jellyfish
jellyfish
Jellyfish is the most familiar transparent animal to the public. Its body is made up of colloidal substances and water (97% of the body), so most of it is transparent. The free-swimming jellyfish looks like a transparent umbrella. The diameter of the umbrella is large and small, and the largest umbrella can reach 2 meters. In the blue ocean, these swimming jellyfish of different colors are very beautiful. Jellyfish are lower coelenterates and carnivores. Jellyfish appeared before dinosaurs, dating back to 650 million years ago. There are many kinds of jellyfish, about 250 species in the world, which are common in the oceans all over the world. People often classify them according to different umbrellas: some umbrellas emit silver light and are called silver jellyfish; Some umbrellas are like a monk's hat, called a monk's hat jellyfish; Some umbrellas are like white sails on a ship, called sail jellyfish; Some are like umbrellas, called umbrella jellyfish; Some umbrellas shine like rosy clouds, called Xiajellyfish.
