تخم شترمرغ
Ostrich eggs
As befits the world's largest bird, the ostrich lays the largest egg of any living bird. Oddly enough, however, the ostrich egg is one of the smallest in relation to the size of the bird. Measuring 17 to 19 cm in length, 14 to 15 cm in width and weighing up to 1 900 g, the ostrich egg is only just over 1 percent of the female's body weight. The eggs vary from white to yellowish white in colour and their hard shiny surface is pitted with superficial pores of various sizes and shape
