How do you stop invasive lionfish? Maybe with a robotic zapper

"The problem with the lionfish is it's like Darwin's nightmare," Oliver Steeds said, standing on the deck of the Baseline Explorer. A late afternoon sun dwindled over the 146-foot research vessel, as it sat anchored in St. George's Harbour on Bermuda's northeast corner. Licks of ocean water dried off a gold-plated submersible parked next to Steeds, the director of a deep ocean exploration project called the Nekton mission, as he recounted the basics of the invasive species. "Lionfish are chowing their way through the food chain, because they don't have any predators," Steeds said. Map of the lionfish spread based on sightings from 1985 to 2015. The first lionfish sightings occurred off the Florida coast in the mid-1980s.
