A gill (/É¡Éªl/) 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.
gill slits appear early in embryonic life among humans and other land-dwellers, for example, helps confir m that gills are a primitive character among vertebrates. (3) The idea that human fetuses have gill slits is a part of what was known as the Biogenetic Law. The idea that the embryo of a complex animal goes through stages resembling the embryos of its ancestors is called the Biogenetic Law. (4) This Law, also known as
