Before you is another educational book from the “Nastya and Nikita” series. It tells about unusual animals, the existence of which was discovered by scientists quite recently. These are the inhabitants of the depths of the sea, mysterious caves, underground burrows and labyrinths, tropical rainforests and mountain forests. All of them are presented here not only in the text, but also in numerous illustrations. The book reveals to children the richness of the animal world of the Earth, reminding them that coming generations will have to discover and describe many new “unseen little animals” in the future.
