La cavitación

The video explains how propellers deteriorate due to cavitation, a process where low-pressure zones cause water to evaporate and form bubbles. These bubbles can damage propellers when they implode, releasing energy as heat and shock waves. Cavitation affects not only propellers but also marine life, such as dolphins, which are limited in speed to avoid damage. Some creatures, like the pistolera prawn, use cavitation to their advantage by creating shock waves to stun prey.
