The crustacean wasn't about to be boiled in a pot without putting up a solid fight firstThis hilarious video has captured the moment a crab threatened a chef - by waving around a knife.

The bizarre footage shows the crustacean scuttling sideways with the sharp object grasped between its pincers.

As the chef gets close to the creature, it waves the knife menacingly, in an attempt to get him to back off.

It is thought the footage was recorded in a restaurant in Brazil although the exact location is not specified.
