Now, it's not like many fish are known for their good looks, often emerging from the deep with bizarre bulging eyes, extreme underbites and weird spikes protruding from their heads.
But things get particularly creepy when one rears its head to show off what look a lot like human teeth - as one recently did over in the United States, going viral online.
Photos of the strange catch were posted on the Facebook page for Jennette's Pier, a fishing hotspot in Nags Head, North Carolina.
The caption simply reads '#bigteethbigtimes'.
Indeed, the large fish can be seen gawping at the camera with its surprisingly strong set of gnashers in one photo, while another snap shows the sheer size of the beast as it's held in both hands by someone.
The post has since racked up 1,200 reactions and hundreds of shares, along with hundreds of comments from weirded-out social media users.
One wrote: "That fish has better teeth than me."
Another said: "That's terrifying."
Tagging their friend, another said: "Fish with people teeth."
A fourth added: "I know people who would love to have that many teeth. Lol."
Many people said they believed the fish is a Sheepshead, although one person was still convinced its teeth were 'human'.
They said: "It is called a sheepshead but those teeth are human so the pic is doctored."
According to the Charlotte Observer, the 9lb fish was caught by a man called Nathan Martin, who had been out fishing with his twin brother on Monday (2 August) when he found a fish with a 'mouth full of teeth'.
Martin, a regular at the pier who had gone out in the hopes of catching a sheepshead, told McClatchy News: "It's a very good fight when you're fighting on the line, it's a really good catch, and it tastes very good."
According to the North Carolina Department of Environmental Quality, Sheepshead fish generally weigh around 5-15lbs, and are around 30in long.
Its website says: "Sheepshead are greenish-gray with a laterally compressed body marked by five or six vertical dark bars on the sides. They have prominent teeth with incisors, molars and rounded grinders that enable them to crush shellfish and sea urchins. They have strong, sharp spines on the dorsal and anal fins."
It adds of their habitat: "Sheepshead are found in saltwater and brackish coastal waters around jetties, wharfs, pilings, shipwrecks and other structures covered with barnacles, mussels and oysters."
