Barreleye- fish with transparent head

Barreleye is a fish that lives at great depths. Her transparent forehead makes her stand out. You can easily see her eyeballs through it.


Until 2009, scientists thought that fish could only see above themselves, but Bruce Robison and Kim Reisenbichler proved that their eyes are movable. 


Like most deep-water fish, changes in their appearance serve to adapt to life at depth. In their case, to notice food floating above them e.g. siphonophores, and to capture more light. The eyes are light green, probably to attract the attention of victims. They are surrounded by a space filled with a transparent liquid. The fish's head is very delicate and only one of many attempts to catch the fish without damage was successful.

One of their most common foods is jelly. They reach up to 10 m in length. They have many stinging tentacles. The space above the eyes protects the fish from burns.



I believe life in the ocean is as exciting as life beyond Earth. Humans have only discovered 5% of the geography of the underwater world.

Strawberry Squid

Strawberry squids are one of the most beautiful ocean creatures I know. It is for sure because of its shining pink skin  which they owe to photophores. We already know ( from the last blog about Barreleye- a fish with a transparent head) that nothing in the ocean is accidental. The ability to bioluminescence is mainly used for communication with other ocean creatures. Another fantastic thing about them is their eyes in two different sizes. The larger yellow eye helps the squid see the shadows of prey swimming above them. The smaller blue eye helps the squid look for light reflecting off other glowing creatures below. Another adaptation is that they swim at an angle, so they can use both eyes. They appear at a maximum depth of 1000 meters and it's during the day when they hide from predators but at night they can be found closer to the surface. Thank you for reading !!!

 Blobfish is a very unfavorable looking fish. When I saw her for the first time, I had many questions. Fish lives at great depths, from 600 to 1,200 m. The pressure underwater at such depth is so great that it would instantly crush human organs. The conditions in which it lives make it difficult to study its species. The fish is small but weighs a lot. It measures 30 cm and weighs as much as 9 kg. It feeds on small organisms found in its environment. It has no teeth. The fish's body is a gelatinous mass.   And now the most important thing, why does the Fish look this way? The answer is not complicated. Fish are adapted to life under enormous pressure. It is what gives her body its shape. A fish pulled out of the depths loses its properties. The nets dragged for more than a kilometer to the surface destroy their bodies. We have very few photos that show us what they look like in their natural environment. However, it is enough to say that they look like completely norma
