the predominant cell of cetacean epidermis , not found in normal terrestrial mammals , is a lipokeratinocyte , which elaborates not only keratin filaments , but also two types of lipid organelles : first , lamellar bodies , morphologically identical to those of terrestrial mammals , are elaborated in great abundance in all suprabasal epidermal layers , forming intercellular lipid bilayers in the stratum corneum interstices : and second , non-membrane-bounded droplets appear and persist in all epidermal layers .
