A photo of the fish was shared on Facebook this week by Jennette’s Pier, a fishing destination in Nag’s Head, North Carolina.
It was identified as a sheepshead fish, which has several rows of molars for crushing prey. The fish appears to have been given its name due to its mouth looking like the mouth of a sheep.
The fish was reportedly reeled in by Nathan Martin, a regular on the pier.
Mr Martin said he had been hoping to catch a sheepshead fish when he came face-to-face with a “mouth full of teeth.”
“It’s a very good fight when you’re fighting on the line, it’s a really good catch, and it tastes very good,” he told McClatchy
The post – captioned with the hashtag #bigteethbigtimes – caused quite a stir.
“Is this where dentures come from?” wrote one user.
“That fish has better teeth than me,” wrote another.
“Wonder how it brushes its teeth,” wrote a commentator on the Facebook page for Jennette’s Pier.
