Moon Jellyfish. They are commonly seen on the shores of North America and Europe. This pink or blue jellyfish usually lives in waters about 20 feet deep. Its sting is mild, leaving a red, itchy rash. It is interesting that jellyfish, unlike human, can reproduce sexually and asexually. Can you suggest ONE scenario when jellyfish prefers to reproduce asexually? Please include one source.
