LIONFISH - Young P. volitans, caught on Long Island, on display at Atlantis Marine World. (Photos by Todd R. Gardner)
I’ve grown somewhat accustomed to seeing these brightly-colored wayward fishes in my underwater wanderings, so when I happened upon a tiny lionfish clinging to a wooden piling along the south shore of Long Island in September, 2001, it took a moment for me to fathom the implications. This was not just a stray from the tropical Atlantic. This fish was way off course.
This is a wonderful article in Advanced Aquarist by Todd Gardner about the discovery of Lionfish in the cold Atlantic waters off Long Island and the possible migration of a species.
