Skins, teeth, feathers, reptile shells, ivory and various other parts of animals have been used by humans as personal adornment since recorded history.
Examples are: the large dog that is abandoned when the owner moves into a smaller apartment or has a baby; peacock and parrot feathers plucked from the bird while alive or dead; living coral and shells collected to be used for jewellery and house decor; seeds and seed heads of plants collected and put to similar use; plants used as interior decor; tropical fish kept in aquaria.
