Living in the depths of the North Pacific ocean macropinna the Smallmouth has a very unusual appearance. Her transparent forehead, through which she could spy out the production of their tubular eyes.
Unique fish opened in 1939. However, at that time did not work well enough to study, in particular the structure of the cylindrical eyes of the fish, which can move from vertical to horizontal and Vice versa. It was done only in 2009.

This camera covers a dense, but at the same time elastic transparent membrane, which is attached to the scales on the body of the Smallmouth macropinna. Bright green eyes of fish due to the presence of a specific yellow pigment. Continue reading
In recent years, studies of the deep sea are very active. However, the oceans keep so many secrets that I reveal have scientists of several generations. There is evidence that to date 99% of the area of the bottom of the oceans of the Earth remain unexplored. However, there are animals, scientists are already open. And most of them boggles the imagination as to their appearance and lifestyle. A large part of deep-sea animals are predators. So, bathysaurus that live in tropical seas, is the predator who has mastered the very deep part of the sea.
He is able to swallow everything that gets in his way. His sharp tongue equipped with teeth, does not give the prey the slightest chance to escape. Bathysaurus not necessary friend of life: nature gave him the genitals of male and female at once. Long and sharp fangs has a fish-Viper.
