To objectively quantify phenotype-environment associations and individual variation in shore crab (Carcinus maenas) camouflage across different habitats and developmental stages.
Conducted field surveys across four locations in Cornwall, UK, sampling predominantly rockpool, mussel bed, and mudflat habitats.
Applied digital image analysis to quantify color and pattern variation among juvenile and adult crabs from diverse background environments.
Crab coloration and patterning exhibited substantial differences across distinct habitat backgrounds, with phenotypic variation mediated by life stage (juvenile versus adult).
Juvenile crabs demonstrated higher levels of individual variation in appearance than adults, whereas individuals from more homogenous habitats exhibited lower phenotypic diversity.

Implication

Observational field study reveals habitat- and ontogeny-dependent camouflage patterns in shore crabs, indicating that local environmental selection shapes individual phenotypic diversity.
