A gross creature which gobbles up a fish's tongue and then replaces it with its own body has been found in Britain for the first time.
The bug - which has the scientific name cymothoa exigua - was discovered inside the mouth of a red snapper bought from a London fishmonger. The 3.5cm creature had grabbed onto the fish's tongue and slowly ate away at it until only a stub was left. It then latched onto the stub and became the fish's "replacement tongue".
