The telescope fish can scare, even the most fearless deep-sea divers. It looks truly creepy.

This fish is able to open its mouth extremely wide, because its individual bones are connected by elastic ligaments with long, razor-sharp teeth, slightly curved inward. There are no scales on the "telescope" body, so it is covered with a substance called guanine. Because of it, the body of the animal shimmers with a greenish-purple color.

But the creepiest thing about a telescope fish is its eyes. They are huge and protrude from the head like binoculars. Despite cloudy pupils, this fish has excellent vision and it is able to see prey even in the most twilight zones of the ocean. "Telescope" can boast vision like eagle has. And yet, it can perceive not only the optical range, but also infrared range.

Habitat

The telescope fish is found in tropical and subtropical waters throughout the world. The territorial waters of some countries where they are most common include New Zealand, Tasmania and Chile. 

People rarely meet these monsters, since the "telescopes" prefer to live at a depth of at least 2000 meters.

In length, the fish reach no more than 20 cm. But, despite its small size, the telescope fish is a ferocious predator. It eats everything on its way.

So far, scientists have been able to study little of this species of fish, since the animals live very deep and are almost impossible to catch.
