It was a breathtaking sight that sparked excitement among some boaters in Milford.
What was believed to be a humpback whale breaching the waters of Long Island Sound was caught on camera.
The whale was spotted in about 20 to 30 feet of water around Charles Island.
The footage was apparently captured by a frequent customer of Bobby J's Bait and Tackle in Milford. The video was posted to social media through the shop's owner.
"You think its a fish story. There's no possible way its a whale, you think its a big fish. You see the video and you can tell, its an actual whale," said Jason Jadach, of Bobby J's Bait and Tackle Shop.
"When I first saw some water coming from the blow hole, we weren't sure what it was, a few seconds later it crashed into the water and we started following," said Mark Tutino, who was out fishing with Jadach when they saw the whale.
Customers reported that they've seen dolphins and even sharks before in those waters, but never a whale.
The sighting happened on Sunday afternoon, according to the post.
"The first time we heard it, we weren't paying attention, so it was kind of shocking. Didn't know what it was," Tutino said. "A few seconds later it breached next to our boat."
Mystic Aquarium officials told Eyewitness News that the behavior is quite normal for humpback whales.
As is the case with most marine mammals, they sought to remind people to use caution and observe them at a safe distance.
