Nature a lot of new species are waiting for us to discover and study, recently scientists found a magical animal, they can be invisible, these magical small animals can not only be invisible but also control the light, unlike due to the use of their own pigments with octopuses, these little guys can be completely invisible, the following picture can you see it, this is the time to test the eyesight, then let's take a look at it.
Take stock of nature's magical invisible animals:
1. Glass octopus
The glass octopus (scientific name: Vitreledonella richardi) got its name because its body is almost completely transparent, this gelatinous octopus can grow up to 45 cm long - if you count the tentacles, they are distributed in tropical and subtropical seas, moving at a depth of between 300 meters and 1000 meters, in addition to the digestive system, optic nerve and eyes, the glass octopus is not the only transparent animal that can camouflage the eyes, many transparent mollusks will use mirror structures to camouflage the eyes, Because the mirror reflects more seawater in the open ocean, the eyes become invisible.
2. Glass squid
The small-headed squid is also known as the small-headed squid. There are also many transparent members of the squid, mainly belonging to the small-headed squid family (Cranchiidae, they are also known as "glass squid"), there are about 60 species, all of which can be seen at a glance, these squid live in various open ocean areas of the world, living depths between 200 meters and 1000 meters, although the body is completely transparent, their large eyes are not transparent, and predators swimming below can easily find the shadows cast by the eyes, but, Glass squid have a clever way of camouflaging, using the luminous bodies under the eyes to create a "counter-illumination" effect.
3. Bottle sea squirt
Bottle sea squirts are almost completely transparent barrel-shaped organisms, their bodies are gelatinous, by inhaling and discharging seawater, they can swim and feed at the same time, bottle sea sheaths rely on filter feeding on phytoplankton in seawater for their livelihood, although they look a bit like jellyfish, they are actually more complex, and more closely related to fish and vertebrates, they also have hearts and gills, can reproduce sexually.
4. Broad muscle new gill bottle
Sometimes, the body is not transparent enough, and the organism needs other ways to keep itself invisible. Another effective method has evolved for the suborder of endpods, tiny crustaceans with transparent bodies and similar shapes to shrimp, but even with a piece of transparent glass, you can detect its presence based on the light reflected above, which is a problem that cannot be ignored in the ocean, because many predators use bioluminescence to search for prey.
5. "Ocean Sapphire" leaf water flea
The most incredible thing about leaf water fleas is that one second they are still shiny, and the next second they suddenly disappear, sapphirina is a type of creature similar to the size of an ant, also known as "ocean sapphire" leaf water fleas (Sapphirina) is a kind of creatures with the size of ants, living in warm tropical and subtropical seas, they belong to a type of crustacean called copepods, different leaf water flea species can emit strange, Fluorescence from bright blue, bright red to gold.
6. Transient butterfly
Most transparent animals live in the ocean, there is a reason, to make the body transparent, you have to be composed of substances that neither absorb light nor reflect light, which is a difficult task for animals and plants on land, because the refractive index between living tissue and air has a very large difference, refractive index describes the rate at which light passes through a certain object, light travels the fastest in a vacuum, and the greater the density of the object, the longer the light penetrates it, the greater its refractive index.
7. Transparent snail
Another example of a transparent land animal is the transparent cave snail (scientific name: Zospeum tholussum), found in the deepest cave in Croatia, where scientists at the University of Frankfurt in Germany have found this snail at a depth of about 980 meters in the Lukina Jama-Trojama cave, living in a rocky and sandy environment, through which a small stream runs.
