Don’t let their cute eyes fool you! The peacock mantis #shrimp has one of the most powerful punches in the animal kingdom. Its club-like appendages can strike with the speed of a bullet, reaching up to 23 metres per second (about 50 miles per hour). This punch is so forceful that it can break through the shells of #crabs, #clams, and even aquarium glass. The speed of the strike also creates cavitation bubbles, which produce a second impact when they collapse, effectively doubling the mantis shrimp's punch power. ~~~~ #ScubaDiving #Liveaboard #DiveTrips #liveaboardlife #MarineBiodiversity #seacritters #UWPMacro

What a treat for our passengers on board Poseidon this afternoon, who had a juvenile (3-4 years) Humpback whale come and join the fun at Helms Deep! The crew kept the passengers who were already in the water in a tight group as the extremely curious Humpback made around 20 passes in a 20 minute period. What an absolute treat for our passengers! We bet they've had a 'whaley' amazing day! 🐋🐋🐋 Thanks to Dan Hill for the 📹 #PoseidonCruises #Australia #ThisisQueensland #ExploreTNQ #CitizensGBR #GreatBarrierReef
