Artificial gills are hypothetical devices to allow a human to be able to take in oxygen from surrounding water. This is speculative technology that has not yet been demonstrated. Natural gills work because most animals with gills are thermoconformers (cold-blooded), so they need much less oxygen than a thermoregulator (warm

In 2018, there were only 66 confirmed unprovoked shark attacks on humans, which is the lowest it's been in years. It's even more rare for the attack to be fatal — last year, the U.S. experienced ...
The gills are composed of comb-like filaments, the gill lamellae, which help increase their surface area for oxygen exchange. [5] When a fish breathes, it draws in a mouthful of water at regular intervals. Then it draws the sides of its throat together, forcing the water through the gill openings, so it passes over the gills to the outside.
The Channel Islands have a long and storied history, with human habitation tracing back thousands of years.
