The red lionfish sports maroon and white stripes to complement its venomous spines. A native of the Indian and Pacific Oceans, the red lionfish and one of its cousins have rapidly established a new domain from Cape Hatteras to the coast of Mexico.

The lionfish gorge on small fish, mollusks and invertebrates, enough to fill out to as much as 480 grams and decimate local populations on the coral reefs they inhabit. Their arrival has caused quote "extreme disruption to native fish communities," according to the International Coral Reef Initiative, which is studying what to do about the lionfish invasion.

The lionfish are largely taking over thanks to overfishing by us humans, which has seriously diminished native grouper and snapper that would otherwise play the same role. But humans can help too, if we just learn to overfish the lionfish.

In fact, the answer to this invasive species problem may lie on the dinner table. After all, lionfish fillets are not poisonous and rather delicious, according to both the U.S. National Oceanic and Atmospheric Administration and fisherfolk who have tasted it. Per NOAA quote "we can't possibly eat too many of them."

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
