A gill is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water and excretes carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. [Emphasis added.]
Yes, I Have 'Gills'
History Charles Darwin listed a number of putative human vestigial features, which he termed rudimentary, in The Descent of Man (1871). These included the muscles of the ear; wisdom teeth; the appendix; the tail bone; body hair; and the semilunar fold in the corner of the eye.

In mammals, they go on to form the structures of the head and neck, but in fish they also help develop into their gills. It's this odd connection that led Neil Shubin, an evolutionary biologist.
Humans With Gills
The palmar grasp reflex is a characteristic behavior of human infants, developing as early as 16 weeks gestational age, when the fetus begins to grasp the umbilical cord in the mother's womb. Early research found that human newborns, relying on their grasp reflex, could hold their own weight for at least 10 seconds when hanging by their hands.

Gills are best known for helping most fish species breathe underwater. But less well known is the fact gills regulate the salt and pH balance of fishes' blood, a vital role played by the kidneys in other animals. Collectively known as ion regulation, this lesser-known gill function has been traditionally thought to have evolved in tandem with breathing.
