Venomous and scary-looking Pacific lionfish are invading the US East coast, as far north as Long Island Sound.
Divers have captured hundreds of lionfish this summer. “For us to be finding that many, there must be thousands and thousands more out there,” said Todd R. Gardner, a biologist at Atlantis Marine World aquarium in Riverhead. “It’s a population explosion.”
Nobody knows how the lionfish arrived, what the impacts are, and whether they'll survive winter's cold water (doubtful).
Increasing Atlantic sightings suggest that lionfish are in the Atlantic to stay, at least in the warmer waters further south.
