CITES - Convention of International Trade in Endangered Species. This was set up to regulate the trade of
species that are endangered or likely to be endangered.
Cloaca - The chamber in the tail where digestive, urinary, and reproductive products are discharged.
Clutch - The name of the group of eggs laid by a female.
Cusp - A sharp projection at the end of the jaw.
E
Egg Binding - A condition when a female turtle is unable to lay her eggs.
Egg Tooth - A small bony projection at the end of the upper jaw of a hatchling turtle used to pierce the egg shell
while hatching.
Estivate - Inactivity during periods of drought and/or high temperatures. This is not to be confused with hibernation.
G
Genetic - Pertaining to genes.
Genus - A category of biological classification ranking between family and species.
Gestation - The period between fertilization and the laying of the eggs.
Gravid - Having eggs.
H
Habitat- An environment where an animal naturally lives.
Hatchling - The turtle just after it leaves its egg.
Herpetology - The study of reptiles and amphibians.
Hibernation - Winter inactivity where specific biological changes occur. Not all chelonians hibernate.
Hinge - A moveable joint in the shell.
Hybrid - An offspring from parents who are not the same species or subspecies.
I
Incubation - The phase of the egg after being laid and before hatching. During this period, it needs proper

M
Marginal scutes - The small scutes along the edge of the carapace.
N
Nares - The openings to the nasal cavity.
