Cetyl palmitate is the ester derived from palmitic acid and cetyl alcohol. It is the primary constituent of spermaceti, the wax found in the skull of sperm whales.[2]

Stony corals, which build the coral reefs, contain large amounts of cetyl palmitate wax in their tissues. Most predators find this wax indigestible.
