The biggest crab ever seen in Britain arrives at Birmingham’s National Sea Life this February half term.

He is a Japanese Spider Crab with a two-metre claw span – big enough to straddle a car.

He has been christened Crabzilla and is set to leave you totally shell-shocked!

The colossal crustacean has been flown to the UK from Japan and is ultimately bound for Belgium to take up permanent residence in a specially adapted display tank the Sea Life centre in Blankenberge.

The National Sea Life Centre’s open-topped ray tank has the icy cold waters Crabzilla needs, and will be his home until the end of March.
