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
The posterior margin of the skull formed an operculum covering the gills. The spiracle was situated in an otic notch behind each eye. Computed tomography has revealed that Ichthyostega had a specialized ear, including a stapes with a unique morphology compared to other tetrapods or to any fish hyomandibula. [5]

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.
Pharyngeal clefts resembling gill slits are transiently present during the embryonic stages of tetrapod development. The presence of pharyngeal arches and clefts in the neck of the developing human embryo famously led Ernst Haeckel to postulate that " ontogeny recapitulates phylogeny "; this hypothesis, while false, contains elements of truth ...
