The three-eyed dinosaur shrimp is not only called a "living fossil", but is also kept as a pet in Japan, Taiwan and other regions.

The three-eyed dinosaur shrimp has strong vitality and has existed for 200 million years. This creature, which has existed on the earth 200 million years ago, is used by many Japanese farmers as a substitute for pesticides in rice cultivation, because the three-eyed dinosaur shrimp can remove weeds in paddy fields, allowing rice to grow better.
