A group of explorers was looking for a kind of fish, which is called the invisible fish. The probability of finding it is very slim. They didn't lose hope and kept looking for it in the ocean. After much exploration, they find it and film the whole process for a documentary they were making about it.
This type of fish is called invisible because all of her body parts are a kind of silvery white that looks invisible. It's like jelly, it's delicate. This kind of fish also is very small, that is why finding it very difficult.
The fish looked sad because it was in the hands of those sea explorers. But after filming, they decided to let it go in the ocean because it belonged to the ocean.
Nature has all kinds of creatures, and specially sea, which sometimes surprises us with its unusual creatures. Who would have thought such a fish could exist.
