10 Most Transparent Animals in The World

1. Transparent Frog
Originally from Venezuela. While the general background color of most frogs is green lime, this animal's skin has a transparent stomach, so that the heart, liver, and digestive tract are visible through their skin.

2. Transparent Fish Head
This strange fish in water is called Barreleye (Macropinna microstoma) has a transparent head and eyes. Two points above the mouth of the fish are not eyes: they are the olfactory organs called nares, which is analogous to the human nose.

3. Transparent Butterfly
Found in Central America, from Mexico to Panama, Glasswing Butterfly (Greta Oto) is a brush-footed butterfly where its wings look like glass.

4. Transparent Squid
Found in the southern hemisphere oceans, Glass Squid (Teuthowenia pellucida) have light organs on the eye and have the ability to roll into a ball, like a sea urchin. This is the prey of many deep-sea fish (eg goblin sharks) as well as whales and oceanic seabirds.

5. Transparent Zebrafish
This see-through zebrafish was created in 2008 by scientists so that they can study the disease process, including the spread of cancer. Fish that are transparent allowing researchers at Children's Hospital Boston to directly view the internal organs of fish and observe processes like tumor growth in real-time in living organisms.

6. Transparent Icefish
Found in the cold waters around Antarctica and southern South America, crocodile icefish (Channichthyidae) eat krill, copepods, and other fish. Their blood is transparent because they do not have hemoglobin and / or simply not functioning erythrocytes. Their metabolism relies only on the oxygen dissolved in blood fluid, which is believed to be absorbed directly through the skin from the water. This works because water can dissolve oxygen during the coldest. In five species, the gene for myoglobin in the muscle also has disappeared, leaving them with a white heart, not pink.

7. Transparent Amphipod
Called Phronima, this unusual animal is one of the many strange species recently found on the expedition to the sea in the mountains in the North Atlantic. The scientists say that the strategy of survival of small shrimplike creature shows everything inside and beyond in an effort to disappear.

8. Transparent larval shrimp
Found in the waters around Hawaii.

9. Transparent salp
This jellyfish-like animal known as Salps, small plants in the water, called phytoplankton (marine algae). They are barrel-shaped animals that can range from one to 10 cm in length.

10. Transparent Jellyfish
Free-swimming jellyfish, member of the phylum Cnidaria. They are found in every ocean, from the surface into the sea. Many of the jellyfish is so transparent that they are almost impossible to see. The one above is from the genus Arctapodema, with a length of one inch (2.5 centimeter-long).
