Woman opens a can of tuna and finds a surprise

Usually opening a can of tuna is a fairly mundane task -- unless you're Zoe Butler. Last month, the mother from Nottingham, UK got a not-so-pleasant surprise inside her can. Now, the mystery creature that she discovered has been identified.

According to the Nottingham Post, it's something called a megalopa, which is described as an "immature crab" that is often eaten by tuna. The megalopa had been nestled in between Princes tuna chunks when Zoe Butler first saw it's dark eyes staring up at her.

A spokesperson for Princes told the Nottingham Post, "We appreciate that the appearance of the crab will have been unpleasant. However, please be assured that it represented no food safety risk."

The company reportedly launched an investigation to determine the species after pictures of it surfaced. Even though it seems like the case is closed, the story is still attracting differing theories.

According to The Telegraph, experts at London's Natural History Museum had a different response concerning the species. Following an examination of the photos, they said the head appears to be that a parasite called a tongue-eating louse.

"I opened the top of the lid and saw a purply thing, a gut sack or intestine. I turned it around and pushed it with a fork and saw it looking back at me," Butler said. "It's got like a spiny tail along the bottom, it's quite grim."

When Butler asked The Nottingham post over Twitter what they thought it was, it turned into the creation of the hashtag #tunagate. Some ideas include a baby crab, a sea slug, or an actual monster.

We're going to go ahead and take tuna off our grocery lists for a while.
