These colourful crabs act like military tanks, as they bulldoze their way across the sea bed, ploughing through anything and everything in sight.
The Puget Sound King Crabs were filmed by photographer and filmmaker, William Drumm, during a diving expedition off Vancouver Island, British Columbia.
These weird looking creatures are vibrant in colour and have very thick shells, making them perfect for stampeding along the ocean floor.
William said: “It was really fascinating to see.
“They don’t care what’s in their way, they just go through it, they have no fear!”
These rare crabs can live at depths of 450 feet and have shells over ten inches wide.
“Urchins, anemones, sea cucumbers; whatever is in their way had better move or get bulldozed!”
