ammocoete - ammocoete
ammocoete - Larva of Lamprey (a cyclostome). See also: Endostyley ammonite. Member of a group of extinct cephalopod molluscs, related to the living pearly nautilus, with chambered shell. Abundant in the Mesozoic. amnion. The embryo of amniote vertebrates (reptiles, birds, mammals) develops in a fluid-filled sac. The wall of this sac has two layers of epithelium with mesoderm and coelomic space between, formed usually by folds of extraembryonic ectoderm and mesoderm which grow up around, and eventually roof over, the embryo. The inner epithelium of the wall is the amnion, though the term is also applied to the whole sac. The outer epithelium is usually called the chorion. Amniotic fluid within the sac provides a fluid environment for the embryo, necessary for animals reproducing on land. In mammals the fluid probably cushions embryo against distortion by maternal organs pressing on it.
