Jellyfish fascinate me! These unusual creatures have drifted along with ocean currents for millions of years, even before dinosaurs roamed the Earth. And despite their name, jellyfish aren’t really fish—they’re invertebrates (animals with no backbones). They have a very short life span; usually less than a year in the wild, although aquarium jellyfish that are carefully tended might live twice that long.
