This fancy decorator crab knows how to intimidate when need be

Scuba diver Jules Casey captured footage in July of this frilly decorator crab who, with its frozen, outstretched stance, was telling her to "Back off!" Known for adorning (aka camouflaging) themselves with found baubles such as seaweed, anemones, and coral, they normally look more cute than intimidating. But Casey wasn't taking any chances. "I was terrified & quickly moved on," she says, followed by a laughing emoji, on her @onebreathdiver Instagram page.
