KM Media Group-owned Whitstable Gazette parodied the classic Jaws film poster this week changing the headline to Claws after reports of a 50ft crab being spotted in the harbour of the popular Kentish coastal town.
The Whistable Gazette T-shirts are being given away in a competition with any profits from the text message revenue being donated to the newspaper's charity of the year.
Editor Leo Whitlock said: "Crabzilla was all that people in Whitstable were talking about with the online versions of the story generating visits from more than 141,000 unique browsers in just a couple of days.
"We knew we had to do something different for the paper so hats off to deputy production editors Lisa Daniels and Crispin Whiting for the front-page idea, head of editorial graphics Ashley Austen for the execution and reporter Mary Louis for suggesting we put it on a T-shirt.
"We've had so much positive feedback about the front that I'm certain people will be tripping over themselves to enter.
"In fact, the people I've mentioned it to have all asked for one for themselves.
"We run so many breaking and hard-hitting stories on the site, it's nice to have a bit of fun."
