Is it a shark? Fin sighted in South Boston bay
SOUTH BOSTON, Mass. (WHDH) -- People who have been hanging around South Boston’s Pleasure Bay recently may have noticed something different in the water: an apparent shark fin.
Video sent to 7News showed the huge fin thrashing back and forth in the water in the bay.
The fisherman who took the video said he has seen it two days in a row.
"Just today it was real huge. It went real out. And it was real huge,” Edgar Marzan said.
The fin was so big, a lot of people thought it must be a shark.
"I did see a shark out there a couple of years ago, but it was only like a 2-foot shark or what have you,” Terrence Stapleton, a kitesurfer at the lagoon, said.
Kitesurfers use the bay all the time, as do boaters and athletes training for triathlons.
The question remained on everyone’s mind though: is it a shark?
"I've never seen one in person, up close, what do I know. Don't expect to see one here. I've seen seals, but no sharks,” Nikita Piankov said.
"It could be a shark. That's what you would think at first. But probably a sunfish,” Tyler Furr said.
At first scientists from the New England Aquarium couldn't say with absolute certainty that it wasn't a shark.
"We're just trying to figure out for sure what it is,” aquarium worker Tony Lacasse said.
After seeing the video Lacasse was able to determine what species of fish the fin truly belonged to.
"It's an ocean sunfish. This particular type of sunfish is called a mola mola,” he said. "It's got a very zig zag, rounded zig zag swim pattern that's very typical of mola mola. It also breached down near the beach, and that's something that a shark wouldn't do."
