Abstract
The King penguin epidermis has a stratum corneum of flattened solidly keratinized cells without basophilic nuclear remnants. It contains keratin bound substances and is without an underlying stratum granulosum. The insunken feather follicles and the thick phospholipid-rich cornified layer appear to be adaptations for aquatic life.
