Reptile eggshell porosity regulates oxygen and carbon dioxide exchange during incubation.
Gharial eggs are deposited in deep nests excavated into sandy riverbanks. The eggshell must balance gas exchange with structural integrity under the weight of overlying substrate. Calcium-rich shells provide rigidity while remaining porous enough for oxygen diffusion. Excessive compaction from heavy machinery or altered sediment composition can disrupt this balance. Shell failure or impaired gas exchange reduces hatching success. The physical properties of sand directly influence embryonic development. Nest construction therefore depends on both behavior and sediment quality.

Eggshell resilience evolved for natural sand pressures, not mechanical compression from vehicles or mining equipment. When sediment structure changes, diffusion rates and moisture retention shift. Even subtle alterations can reduce hatch rates significantly. Nest depth becomes a calculated compromise between thermal stability and oxygen supply.
Reproductive success hinges on the microscopic interaction between shell and sand. Habitat degradation that appears superficial can disrupt embryonic physiology. Protecting nesting banks requires understanding sediment dynamics at granular levels. The survival of a massive predator begins with millimeter-scale structural precision.
