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
Nach dem Dichtringe-Wechsel am Propellerschaft stand ich vor der letzten Hürde - 9 Liter Öl wieder ins C-Drive zu bekommen. Das Ausdehnungsgefäß hängt so absurd eng unter der Decke, dass kein Kanister direkt rankommt. Mit einem improvisierten System aus langem Schlauch und Trichter gelang mir der letzte Akt dieser technischen Odyssee. Doch endlich ist es geschafft! #Segelyacht #amel #diyproject
