When were jelly fish discovered?

Answer 1

Jellyfish have existed for millions of years, with fossil evidence suggesting they date back at least 500 million years to the Cambrian period. However, the first formal scientific descriptions of jellyfish began in the 18th century, with naturalists like Carl Linnaeus classifying them. Their long history predates human discovery, as they have been a part of marine ecosystems long before humans began studying them.
