Moment crab armed with knife threatens man and his dog (video)

A shocking footage captures the moment a knife-wielding crab showed up at a man’s house and threatened his dog. 
Eduardo Alvarez shared a video of the weird encounter at his home in Florida, US on Instagram. 
The video shows Eduardo’s pet dog Summer sniffing at the crab, before leaping back when the crab showed its blade. 
 

The crab moved a bit from side-to-side, as though preparing for a fight with the dog. 
After a few moments, Eduardo picked up the crab and dumped into the garden. 
 

Throughout the video, the crab continued clutching its blade – refusing to drop the weapon even when being swung through the air. 
“Dude, are you f*****g kidding me?” Eduardo said as he lifted the crab from his door. 
 

The video was captioned: “Florida is getting out of hand.” 
“Summer, I don’t recommend messing with this,” he warned his dog. “This is like a gangster-a** crab.” 
The viral clip has been watched thousands of times on Instagram, with viewers sharing their thoughts about the dramatic moment. 
See the video below.

🇺🇸 If you’re in Florida, beware. There’s apparently a crab mafia boss roaming around with a shank.

A blue land crab was caught waving a pocket knife and taking swipes at a man’s dog.

Nobody knows where he got the knife, and frankly, nobody should ask.
