Information:  - The coconut tree ("Cocos nucifera") is a member of the family Arecaceae (palm family) and the only species of the genus "Cocos". The term coconut can refer to the whole coconut palm or the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word "coco" meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.  - A mammary gland is an exocrine gland in mammals that produces milk to feed young offspring. Mammals get their name from the word "mammary". The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, and deer), and the dugs of other animals (for example, dogs and cats). Lactorrhea, the occasional production of milk by the glands, can occur in any mammal, but in most mammals lactation, the production of enough milk for nursing, occurs only in phenotypic females who have gestated in recent months or years. It is directed by hormonal guidance from sex steroids. In a few mammalian species, male lactation can occur.  - Coconut milk is the liquid that comes from the grated meat of a brown coconut . It should not be confused with coconut water . The color and rich taste of coconut milk can be attributed to the high oil content . Most of the fat is saturated fat . Coconut milk is a very popular food ingredient used in Southeast Asia , South Asia , Southern China , the Caribbean and north of South America .  - Coconut water is the clear liquid inside young green coconuts (fruits of the coconut palm). In early development, it serves as a suspension for the endosperm of the coconut during the nuclear phase of development. As growth continues, the endosperm matures into its cellular phase and deposits into the rind of the coconut meat.  - Milk is a pale liquid produced by the mammary glands of mammals. It is the primary source of nutrition for infant mammals (including humans who breastfeed) before they are able to digest other types of food. Early-lactation milk contains colostrum, which carries the mother's antibodies to its young and can reduce the risk of many diseases. It contains many other nutrients including protein and lactose.    Given the information, choose the subject and object entities that have the relation of 'natural product of taxon'.
