turtle shells
Natural protective domes
Turtle shells are the hard, protective outer coverings of turtles and tortoises, fused to the spine and ribcage.
The domed upper portion is the carapace; the flat underside is the plastron.
Shells vary by species—some are rigid and bony, others leathery and flexible.
Historically, turtle shells were used for combs, jewelry, and decorative objects, though trade is now largely banned.
Figuratively, retreating into one's shell means withdrawing socially.
