clam shell
Hinged sea casing
A clamshell is the hinged two-part shell of a clam, opening and closing on a single axis.
The shape extends to containers, cases, and devices that open the same way: a clamshell phone, a clamshell food container.
In excavation, a clamshell is a bucket with two hinged jaws for digging.
