10 Totally Transparent Marine Animals

   Transparency is a rather common characteristic among open-ocean living marine animals. Because there are few structures to hide behind in the open ocean, many creatures that dwell there employ transparency as a form of camouflage to avoid predators. Some marine predators employ transparency to aid in the capture of unwitting victims.
 

 1. Barreleye Fish

This deep-sea dweller, sometimes known as the spook fish, can be found in the tropical-temperate seas of the Atlantic, Pacific, and Indian Oceans. The barreleye fish can capture even more light in the deepest of depths because to its huge tubular eyes and dome-shaped, transparent skull.

2. Sea Salp

The sea salp is a planktonic tunicate. The barrel-shaped organism uses jet propulsion to move across the water by pumping water through its body. For their phytoplankton food source, the filter feeders strain the water. Sea salps are most typically found in the Southern Ocean, where they can be found single or in extended chains.

3. Big Skate

There's nothing surprising about this. The giant skate is the largest skate species, and it may be found all along the Pacific coast (from Baja California to Alaska). Their very light skin allows their internal organs to be visible.

4. Sea Walnut

The sea walnut is a comb jelly species with an oval-shaped, lobed body and four rows of ciliated combs running vertically down the body. This insect is not only translucent, but its ciliated combs also illuminate blue-green when disturbed.

 5. Glass Octopus

Despite the fact that the transparent and gelatinous species has only been captured on video a few times, the glass octopus is found in tropical and subtropical seas all over the world.

6. Crocodile Icefish

Crocodile icefish are ambush predators, which means they may go a long period between feedings and eat up to half of their body length in fish. As a result, being open and honest comes in handy. Because their blood lacks hemoglobin, they are sometimes known as white-blooded fish.

7. Glass Squid

Glass squids belong to the Chranchiidae family, which includes roughly 60 species. In the partially illuminated shallow waters, their transparency is a useful camouflaging weapon. Many species have glowing light organs behind their eyes and are bioluminescent.

 8. Transparent Sea Cucumber

The translucent sea cucumber is an almost alien-like organism that dwells about 2,750 meters beneath the ocean's surface. It moves at a rate of 2 cm per minute down the ocean floor using its many tentacles. It's not quite the speed of light.

 9. Jellyfish

These free-swimming, buoyant, umbrella-shaped critters are an aquatic favorite and can be found in any ocean. The sting of a jellyfish is dreaded on beaches all around the world, making the translucent type an even greater danger to swimmers.

10. Sea Angel

The shells of these tiny swimming sea slugs were replaced by a pair of flapping appendages. The largest and most translucent of the gelatinous species is only approximately 5 cm long. Sea angels may swim at speeds of up to 100 meters per second, outpacing their even smaller prey, the sea butterfly.
