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
Artificial gills may refer to: Imitation gills put into stuffed fish for the sake of appearance in taxidermy; An inaccurate term for liquid breathing sets; Artificial gills (human), which extract oxygen from water to supply a human diver
A Business Insider video about preauricular sinus points out that evolutionary biologist Neil Shubin suspects "these holes could be evolutionary remnant of fish gills."
Ileum, caecum and colon of rabbit, showing Appendix vermiformis on fully functional caecum The human vermiform appendix on the vestigial caecum. The appendix was once believed to be a vestige of a redundant organ that in ancestral species had digestive functions, much as it still does in extant species in which intestinal flora hydrolyze cellulose and similar indigestible plant materials.

Triton, "the world's first artificial gills technology" is a Swedish and Korean organization that claims they have created artificial gills for humans. [1] Released as an Indiegogo project on March 14, 2016, this technology claims to allow divers to spend 45 minutes underwater at depths of less than 15 feet.
“Maybe the reason why we have this condition in humans is because of this trade-off that our ancestors made 25 million years ago to lose their tails,” Yanai said.
View of stipe, gills, and cap of Z. illinitus. Cap : It has approximately 2–7 cm long radius. It is round becoming convex then wide or with a broad umbo, the margin hanging with slimy veil remnants. It is white or cream in color. It feels smooth and sticky or slimy. [9] [10] Gills : They are free, non-waxy, close, broad and white in color. [9 ...
The event is well-documented [1] and important [2] [3] academically as a demonstration of transitional forms and exaptation, the re-purposing of existing structures during evolution. [ 4 ] The ossicles evolved from skull bones present in most tetrapods , including amphibians , sauropsids (which include extant reptiles and birds ) and early ...
