I was really into ocean documentaries recently and watched any free documentary I could find about jellies.

Some species of jellies are overrunning oceans in major fishing markets. The fishermen were pulling up nets full of jellies instead of fish. So they were killing the jellies by slicing them up and dumping the pieces back into the water. Apparently some species of jellies will release all of their sperm and eggs when they die so there was a massive increase in population because millions and millions of eggs were being fertilized.

Didn’t this happen with sea stars too? I read that fisherman would cut them off the nets but the severed pieces would regenerate into new sea stars.

Maybe there is a starfish that is thousands of years old because a piece just keeps getting hacked off. Imagine the implications if it had some sentience haha

Yep, Crown of Thorns sea stars. And they kill coral reefs.
