Plastron

The plastron is the ventral (underside) shell of a turtle or tortoise. It's a bony structure composed of several plates, providing protection to the animal's internal organs. The specific shape and pattern of the plastron can vary greatly between species, aiding in their identification. It often articulates with the carapace (dorsal shell) via a bridge of bone or cartilage, forming a rigid box that safeguards the animal. Its markings can change with age and sex, adding more identifying features. This shield-like structure plays a crucial role in the animal's defense and survival. This vital structure allows for locomotion and protection from predators and environmental dangers.
