Are There Transparent Animals?

Are There Transparent Animals?

There are many animals that are transparent, especially under water, where transparency helps water creatures to hide from predators.

All animals strive for the same survival. We people may not always have to watch, but other animals certainly have to, especially those who are at the top of the menu for predators that surround them. It is difficult to survive because not everyone can be at the top of the food chain.

Of course, some animals have found a clever way to deceive their predators, and they disguise themselves, but it also has its drawbacks: What if there is no substrate on which to disguise themselves, and there is nowhere to hide?

To combat this problem, some animals have evolved just to hide in plain sight!

Transparent... but how?

If transparency provides first-rate protection against predators who want to track you down, why don't we face invisible creatures all the time?

Animals are made up of many organs and tissues that have their thickness and chemical composition.

Water users have a clear advantage in terms of transparency, since their bodies are almost entirely water-based, but being transparent to a landowner is much more difficult because of the refraction factor.

The air we breathe has a very low refractation rate, but the water has a much higher value. Think about looking at a glass glass on a sunny day... it's probably got a blinker on it, isn't it? What if you put the same glass in the water? Call it a crystal, because it's just as transparent.

So if the water has a high refractation rate, like the material that some oceanic animals make up, the light doesn't scatter much, and suddenly, bam, you don't see them anymore.

If you think about it, transparency is the perfect form of camouflage.

Animals using transparency to hunt

Low-income macropine

Macropinna Microstoma, also called a ghost fish, was well described by a marine biologist, Dr. Helen Skales, as a fish with "a transparent bladder helmet similar to an astronaut's helmet." There is a good reason for this difference because this fish has a dark, non-transparent body, but transparent head through which its eyes and other organs can be seen.

Ghost fish's eyes are green glowing balls, and they always look up, hoping to catch the shadows cast by their prey when they are hit by glowing sunlight. If you're wondering how they eat when they look up, they just turn them inside their dome out of transparent tissue.

Animals who use transparency to save themselves from predators.

European eels

And when they reach the age of four, they say, "Silver eels," and when they reach the age of four, they say, "Silver eels," and "Silver," and "Silver," and "Silver," and "Silver," and "Silver," and "Silver," and "Silver," and "Silver," and "Silver," and "Silver," and "Silver," and "Silver," and "Silver," and "Silent."

Salpes

These are rare marine invertebrates living in the cooler waters of the Southern Ocean. They probably need more transparent bodies than any other fish because they feed on plankton on the surface of the water, making them extremely vulnerable to predators. Salpa is a jelly-like animal covered with a transparent shell that contains muscles, intestines and other organs.

Transparent immortal jellyfish

Turritopsis dohrnii is also transparent and slightly smaller than the fingernail of your pinkie.

Not only do they use their transparency to save themselves from predators, but they also rip off jackpots on survival. One thing is to get out of a harsh environment alive, and another thing is to push the reboot button when faced with imminent death. That's how these jellyfish never die, but are reborn in a polyp phase and continue to live forever!

Ghost shrimp

Ghost shrimp has a pretty nice name, considering how transparent they are. You can only see the orange or yellow spot in the center of their tail. Females are so transparent that after breeding, their green eggs are clearly visible inside their body.

Glass octopus

Vitreledonella richardi or a rare glass octopus is almost entirely transparent, except for eye nerves, eyeballs and digestive tracts. They have long, long eyes with centralized lens that can be useful for minimizing eye silhouette at the bottom.

Calmar-cadadu

These clams, also known as glass squids, are so transparent that the only bursts of color you will see in them come from their eyes and some viscral kernels. However, a feature of this type of squid is that when they are disturbed, they inflate water and release ink inside themselves, quickly becoming a not very visible, non-translucative creature in the twinkling moment of the eye.

This is an impressive way of masking both octopus and squid, and it's a device that keeps several types of predators at a distance. The first predators are those that hide in the sea depths and keep looking up, hoping to capture any prey that appears in the smallest shadow. The second predators are those that cover their prey with "biological" headlamps, they're bioluminescents.

Those who can turn from invisible to non-transparent, octopuses and squids can deceive both kinds of predators.

On land, transparency is much less common, but, as always, there are exceptions. From the moths of Clearwing, whose transparent wings allow them to blend with the background, to the glass frogs, which allow us to look into their intestines, into their bones, and even into their tiny beating hearts, life on land also seems to have adapted effective cloaking techniques through transparency.

Of all the superpowers the animal has, the ability to become invisible is one of the coolest!
