A hatcling is any animal that is newborn from a hard shell. Turtles are born from a hard shell cover. Thus, it should be called a hatchling. A hatchling is the newborn of animals that develop and emerge from within hard-shell eggs. The offspring of birds and reptiles are often hatched naked and with their eyes closed.
A turtle is an animal in armor. Much of its body lies within a protective shell, which has openings for the turtle's four chunky legs, short tail, and head. When danger threatens, many turtles pull legs, tail, and head into the shell. But unlike some animals that live in shells, such as hermit crabs and snails, a turtle cannot crawl out of its shell. The shell is part of the turtle's body. All turtles belong to the class of backboned animals known as reptiles. This class also includes snakes, lizards, and crocodiles.
