Introduction Why are many deep-sea fish transparent? ? Due to the lack of light in the deep sea, many fish can emit their own light to sense the environment. A transparent body has a much better stealth effect than an opaque body.

Why are many deep-sea fish transparent?

? Due to the lack of light in the deep sea, many fish can emit their own light to detect the environment. A transparent body is much more invisible than an opaque body and is more conducive to detection. It is common to evolve into a transparent body on earth. Transparent organisms are also common in freshwater caves. There is no light in the deep sea, so there are generally no deep-sea biological communities. the remains of animals and plants deposited in the upper ocean, and eat each other. Only the sulfide bacteria close to the underwater crater are autotrophic, relying on sulfides to synthesize energy.

Not all? deep-sea animals are transparent, and the bodies of deep-sea animals are usually gray or even black, and sometimes bright red. If he is transparent, this may be due to the following reasons: there is no sunlight on the seabed, so animals do not need body color for camouflage, there is no sunlight in the sea ​​and the fish itself emits it; light (containing fluorescent substances) and transparency or white are intended to reduce light absorption.

Ocean animals generally have a very keen sense of smell and are particularly sensitive to proteins. Rather than recognizing the appearance of their prey, they prefer to smell their proteins. In fact, in the deep sea, because infrared rays emitted in sea water are immediately absorbed by sea water, even red rays look like black in the sea. At 2,000 meters underwater, where even ultraviolet rays cannot reach, most fish and shellfish are light brown in color. In the dark depths of the sea, predators cannot see anything, whether it is black, red or transparent.

?Manymarine animalsuse transparent body tissues when young . Avoid larger predators and fish are no exception. Flat bodies, delicious taste and transparency will not stay with them throughout their lives. As young flounder grow, they will use other methods to protect them. However, its flat body remains an advantage. Flounder hide quietly on the sandy seabed, making it difficult for predators to detect them.
