A fisherman has stunned social media users after sharing a video of a fish he caught which had another smaller fish inside its mouth.
In the clip, which has been shared to Instagram, a catfish can be seen with a smaller haddock hanging out of its mouth.
The fisherman, who presumably caught the fish, then pulls at the haddock while wearing red gloves and finds only the head remains – with the rest most likely digested by the catfish.
The unusual discovery was made by Roman Fedortsov, 39, from Murmansk, Russia, who has left Instagram users in shock.
He captioned the video: "The catfish had recently eaten haddock, in this case it had been swallowed, but did not have time to digest.
"Very often, when cutting large fish, we find slightly overcooked small fish in their stomachs."
Instagram users were quick to share their thoughts.
“I'm scared again," said one user.
“That was a pretty good last meal for the fish!” said someone else.
“Double RIP," joked a third user.
“I thought you were removing with lobster claws," asked another person.
"The food chain is too fast," added someone else.
"2 for 1," wrote another user, adding a fire emoji.
Another Instagram user shared a similar experience, writing: "As a child, my grandfather got a pike, there were 12 small ones inside.
"All along, exactly like a tin can of sprat."
Back in 2015, the Mirror reported on a substantially bigger fish which a fisherman cut open to find another massive one inside its belly.
The footage shows the man using a knife to slice down the middle of his catch, thought to be a marlin, while other fisherman stand around.
It takes several slices through its thick skin before the face of another huge fish, believed to be a 22kg tuna being used as bait, appears in the gap.
With the tug of its fin, the fish then slips out and onto the deck of the boat.
The video was posted on the Facebook page of "Whitiangler", where news from Whitianga and North on the Coromandel Peninsula, New Zealand, is shared.
The caption says: "22KG TUNA LIVEBAIT!!?
"Next time you think your livebait might be 'too big' remember this clip!!
"Unbelievable!!"
