New Yorkers gazing at the East River last week were treated with a surprising and delightful sight: a group of dolphins swimming through the water.
Captured on camera by a sightseer near WNYC Transmitter Park in Brooklyn, the dolphins can be see seen swimming in New York’s once famously polluted East River — offering an optimistic reminder that the body of water has become a lot cleaner than it was a century ago when the river was a site for industrial pollution.
The video, depicting a trio of dolphins graciously swimming in the river, was first posted on Twitter by social media user Cailin Anne last Tuesday, after which it didn’t take long for the video to go viral and be shared thousands of times. You can watch it for yourself here.
