Take a very close look at these wonderful living beings. Why very attentive? Because they are transparent and almost invisible. Wondering why so many of them live in the sea? This is a matter of survival and self-preservation. Biologist Zenke Jonsen explains it this way: "Almost all vulnerable ocean animals, not armed with teeth and toxins, unable to develop speed and are small in size, must be partially invisible to survive."
This transparent fish is the fry of the surgeon fish. They are found in many waters, including off the coast of New Zealand. This is the same type of fish as the Dory fish from Finding Nemo. The surgeon fish can grow up to 30 cm in length and is very popular as aquarium fish.
This fish was caught near the Karikari Peninsula in northern New Zealand. Experts believe that this is SalpMaxima, which is commonly found in the Southern Ocean.
It is a species of frog from the jumping family of Hyperolids. In the Republic of the Congo, such a frog is considered an endemic species. At one time it was considered completely extinct, but in 2011, a transparent jumping frog was discovered and photographed on the banks of the Elila River (a tributary of the Lualaba) during an expedition led by Eli Greenbaum from the University of Texas El Paso.
This beetle is not completely transparent, but it has a shell that is almost invisible. The purpose of the transparent outer shell is to deceive predators, as there are special warning marks on the beetle's back. Turtle beetles are of different types, and the pattern under their transparent shell can also be different, but still very beautiful.
Smallmouth Macropinna is the only species of fish from the genus Macropinna, belonging to the opisthoproctaceous family. The fish has a very unusual transparent and liquid-filled dome on its head through which its tubular eyes can be viewed. This fish has been known to science since 1939, but until 2004 it was not possible to photograph it with high quality. Old pictures cannot convey the transparency of the fish dome, which collapses outside the water.
European eels change color several times throughout their life. At first they are transparent, then on the sides and on the abdomen they become brownish-yellow. After living in fresh river water for about 10 years, eels reach sexual maturity and go to spawn in the sea. Their eyes become larger, their sides acquire a silvery color, and their abdomens become white. At this stage, these fish are called silver eels.
Pharaonic ant (Monomorium pharaonis) is a small (2 mm) yellow or light brown, almost transparent ant. It is considered the most unpleasant pest living in houses. Pharaonic ant (its origin is unknown) lives in almost all parts of the world, including Europe, North and South America, Australia and Southeast Asia.
The transparency of the wings of this butterfly, called Gretoto, is the result of a combination of three properties: first, due to the low absorption of visible light by the tissues of its wings; secondly, due to the weak scattering of light passing through the wings; and, finally, due to the weak reflection of light falling on the surface of the wing. Adult butterflies are mainly found in Central and South America, all the way to southern Chile. They can migrate long distances and have even been seen in northern Mexico and Texas.
This tiny octopus is only 2 centimeters in diameter, and internal organs are visible through its transparent body. He hit the lens at night at a depth off the coast of Tahiti. The orange spots on its tentacles change color and are used for camouflage.
This is still a small squid, or rather a large-winged firefly squid (Ancistrocheirus lesueurii). Its transparent body is covered with pea cells filled with pigment, and bioluminescent glowing organs are located just below the eyes. Firefly squids live in tropical and subtropical oceans at depths of 200 to 1000 meters.
Glass frogs are frogs in the amphibian family Centrolenidae. Although the general background color of most glass frogs is mainly green, or rather even lime, the skin of the abdomen of some members of this family is translucent. Through it, all the insides are clearly visible, including the heart, liver and gastrointestinal tract - hence their name.
Ghost shrimp is a name applied to at least three different types of carapaces: Thalassinidea, mole crayfish that live in deep burrows in the intertidal zone; Palaemonetes, small and transparent shrimp, popular in freshwater aquariums; and Caprellidae, thin-bodied amphipods or amphipods, better known as skeletal shrimps. Ghost shrimp are often attacked by fish, even smaller in size.
The La Palma glass frog (Hyalinobatrachium valerioi) is a species of frog in the Centrolenidae family. They live in central Costa Rica and further south to Panama, as well as in the lowlands of the Pacific coast and on the slopes of western Colombia and Ecuador. The abdominal surface of the frog is transparent, but the heart is covered with white tissue and is not visible.
The immortal jellyfish (Turritopsis dohrni) is a type of small, biologically immortal jellyfish found in the Mediterranean Sea and the waters of Japan. This is one of the most famous cases in the fauna, when a living creature, having reached puberty, is able to completely return to the colonial stage of development in the form of a polyp.
These are Costa Rican tadpoles. The spirals that you see on their abdomens are not a drawing, they are neatly twisted intestines.
