The royal couple was offered the edible saltwater clam at a food and wine festival in British Columbia during a royal tour of Canada. The creature has a lifespan of around 140 years, and its "neck" can extend to almost 1 meters (3.3 ft) in length.

In a Telegraph article, Prince William is quoted as saying about the clams, “Presentationally they are quite challenging,” while the Duchess called them "really unusual."

Ladies and gentlemen, diplomacy at its absolute finest.
