@ausgeo: Watch out! This little guy may look pretty, but mantis shrimps are highly aggressive crustaceans that capture prey using large, raptorial claws. Although these little guys reach only 15cm in length, they can throw punches at speeds of around 80km/hour, which is so fast it can emit a flash of light! You don't want to be a periwinkle or a crab when a hungry mantis shrimp is around and ready to throw hands (or claws!). 🎥 Sidey the Shark #shrimp #colourful #ocean #underwaterphotography #sealife #lobster #crab #crustacean #marine #marinephotography #fish #macrophotography #underwater
