Flexible-shelled

Describing an organism or object possessing a shell or outer covering that is capable of bending, yielding, or changing shape under pressure or external forces, rather than being rigid or brittle. This flexibility allows the shelled structure to absorb impacts, conform to uneven surfaces, or accommodate internal growth. The degree of flexibility can vary greatly, ranging from slight pliability to significant deformation. This characteristic often relates to the organism's survival and adaptability in its environment.

Flexible-shelled meaning with examples

• The turtle, its flexible-shelled body a marvel of evolutionary design, could squeeze into tight spaces to escape predators and navigate narrow waterways. Its shell, not a rigid shield, absorbed impacts from rocks and other underwater obstacles, providing excellent protection while allowing for movement. The shell’s flexibility also aided in burrowing into muddy bottoms.
• Early research focused on creating a flexible-shelled material for military helmets that could disperse the energy of a projectile upon impact, potentially reducing blunt force trauma. Researchers experimented with various compositions hoping to create a balance between protection and comfort. This could be applied to many facets of the body.
• The slow-growing mollusk species were particularly vulnerable because they did not have the added protection of a flexible-shelled approach. The shell material didn’t absorb impact efficiently, and they were heavily preyed upon by species with shells that would not break easily. Thus, the slower growth rate made the mollusk vulnerable.
• When studying the eggs of the reptile species, scientists realized that the thin, flexible-shelled eggs could still withstand incredible pressures from being buried under sand while also allowing the hatchlings to break free. These shells had the resilience to provide protection during incubation.
