Colours and patterns in feathers serve as protective coloration for sexual display.

Countless numbers of them deep and shallow together with pores give every region body characteristic topography. The outstanding feature of sebaceous glands is their holocrine mode secretion involving complete disintegration cells. Those on palms and soles which appear first are present in all but the hooved mammals may be more ancient hairy skin respond to thermal stimuli recent organs
