The relentless scourge of lionfish has crept to unexpected depths: Off the coast of Florida, researchers say they found the venomous invader thriving around a sunken ship at 300 feet (91 meters) below the water's surface.
"We expected some populations of lionfish at that depth, but their numbers and size were a surprise," researcher Stephanie Green, of Oregon State University, said in a statement.
Last month, Green and colleagues investigated the seafloor near Fort Lauderdale, Fla., in a deep-diving Antipodes sub. At 300 feet (91 m) deep, the team witnessed a large number of the spiny fish near the intentionally sunken Bill Boyd cargo ship, an artificial reef created in 1986.
