Eric Osinskie caught a strange animal with his fishing rod over Memorial Day weekend, and shared his bizarre find online. It has certainly caused a stir.

On his fishing excursion, he took a photo of the strange looking creature and shared it on the Facebook page of Catskill Outdoors fishing club.

Eric said he had just wanted to catch some trout in Catskill Creek. Unfortunately, he wasn't lucky that day, as the fish just wouldn't bite. But then, he caught something more remarkable.

"Went fishing for the fish that seem to always be right out of my grasp... but I did catch a new species today," Eric wrote in his post showing off menacing looking photos, which ignited some wild discussion.

But what exactly was this strange animal?
