+ | The cavitation bubbles created by shrimp in stunning their prey have some surprising properties. | ||
+ | Snapping shrimp produce a loud crackling noise1, that is intense enough to disturb underwater communication. This sound originates from the violent collapse of a large cavitation bubble generated under the tensile forces of a high-velocity water jet formed when the shrimp' | ||

Argyroneta Aquatica: This is the only spider known to live permanently underwater. The spider can swim with ease and constructs an inverted retreat which it fills with air. This is accomplished by trapping air on the abdomen. The air is collected from the surface with a flick of the rear legs. At the retreat the air is brushed off, several journeys are required to fill the " | Argyroneta Aquatica: This is the only spider known to live permanently underwater.

- | The Globe Fish lives in shallow water and uses its swim bladder to ascend and decend in the water. The swim bladder is a sac inside the abdomen that contains gas. If you have caught a fish and wondered why its eyes are bulging from its head, it is because the air in the swim bladder has expanded and is pushing against the back of its eye. The gas in the swim bladder is mostly oxygen. Nitrogen and carbon dioxide are also present. De zwemblaas stelt de vis in staat om zijn massadichtheid continu aan te passen en het lichaam in de gewenste positie te houden zonder dat de vis verder energie hoeft te verbruiken met zwembewegingen. | + | The Globe Fish lives in shallow water and uses its swim bladder to ascend and decend in the water.
