Editing Jellyfish (section)

=== Predation ===
Other species of jellyfish are among the most common and important jellyfish predators. Sea anemones may eat jellyfish that drift into their range. Other predators include [[tuna]]s, sharks, [[swordfish]], sea turtles and penguins.<ref>{{cite news | last=Yin | first=Steph | date=September 29, 2017 | title=Who's Eating Jellyfish?

Once jellyfish have become dominant in an ecosystem, for example through overfishing which removes predators of jellyfish larvae, there may be no obvious way for the previous balance to be restored: they eat fish eggs and juvenile fish, and compete with fish for food, preventing fish stocks from recovering.<ref>{{cite book |author=Gershwin, Lisa-Ann |title=Stung!: On Jellyfish Blooms and the Future of the Ocean |url={{google books |plainurl=y |id=4jEJKlpSVf8C|page=274}} |year=2013 |publisher=University of Chicago Press |isbn=978-0-226-02010-5 |pages=274–|url-status=live |archive-url=https://web.archive.org/web/20160806072537/https://books.google.com/books?id=4jEJKlpSVf8C&pg=PA274 |archive-date=6 August 2016}}</ref>
