A horrified woman opened a can of tuna to discover a pair of beady eyes staring back at her. Zoe Butler was shocked after she found the mystery sea creature in a Princes tuna can. The 28-year-old from Nottingham, UK, has since complained and sent a picture of the fishy find to the brand who have now promised to investigate the grim discovery.She said: “I opened the top of the lid and saw a purply thing, a gut sack or intestine, then I turned it round and pushed it with a fork and saw it looking back at me. “It’s got like a spiny tail along the bottom, it’s quite grim. I dropped the fork, jumped back, screamed a bit and shouted for my nan to come and have a look. “I haven’t shown it to the kids because they might get put off eating tuna. I just want to find out what it is and to make sure it doesn’t happen to somebody else.
