Long Islanders thought winter had arrived early when they walked near the Shinnecock Canal in Hampton Bays, New York, on Monday. The water looked like it was covered in a thick sheet of ice, but upon closer examination, residents could see it was actually thousands of silver bunker fish wiggling on top of each other, struggling to survive. Dozens of people posted pictures and videos of the unusual sight on Facebook. “Strange phenomenon. Cause of man or nature?” local resident Gustavo Zuluaga Buritica asked. “Wow never seen anything like it!” Long Islander Eric Reilly commented. As videos of the rare sight go viral, people are now looking for answers.
