Altriciality

In biology, altricial species are those in which the young are underdeveloped at the time of birth, but with the aid of their parents mature after birth. The word is derived from the Latin root alere, meaning "to nurse, to rear, or to nourish" and indicates the need for young to be fed and taken care of for a long duration. By contrast, species whose young are immediately or quickly mobile are called precocial.
