@dailymail: A Florida man had an unexpected run-in with a crab after the unusual creature appeared to wave a blade at his dog in a bizarre moment caught on camera. Eduardo Alvarez was filming when his dog, Summer, approached the crab, which appeared to swipe toward the pup while holding the small blade in one claw. Alvarez quickly stepped in and managed to grab the feisty crustacean, moving it farther into his yard while joking that it was a 'gangster-a** crab.' The bizarre footage has since gone viral, racking up millions of views and leaving viewers stunned by the unlikely encounter. 🎥 @bestdad_ceo #viral #crab #usa #animals #florida
