There are three main categories of newborn maturation that different species of mammals exhibit. Altricial young (marsupials, rodents) are completely helpless and dependent on their mothers, precocial young (elephants, cattle) have highly developed sensory and motor functions at birth, and primates who are semi-helpless young, have an ...

The non-descendant young in whom the alloparent invests can be conspecific (of the same species) or heterospecific (of a different species), a phenomenon often observed in fish and a select number of bird species. [2] There is some debate as to whether interspecific alloparenting (caring for the young of another species) constitutes 'true ...
Different species are physiologically adapted to consume different foods that must be acquired in different ways, and the manner in which they feed must correspond to these unique characteristics. Rodents share common species-typical feeding behaviors (also known as order-typical, since all these creatures are members of the same order, rodentia ).
Breast, bottle, whatever: How You Feed is a shame-free series on how babies eat. Ten years ago, Time magazine's cover featured mom Jamie Lynne Grumet with her 4-year-old son nursing while standing ...
Desert Spider, Stegodyphus lineatus, one of the best-described species that participates in matriphagy Matriphagy is the consumption of the mother by her offspring. [1] [2] The behavior generally takes place within the first few weeks of life and has been documented in some species of insects, nematode worms, pseudoscorpions, and other arachnids as well as in caecilian amphibians.
Interspecific feeding refers to behaviour reported in wild animals, particularly birds where adults of one species feed the young of another species. This usually excludes the case of birds feeding brood parasites. The behaviour has been of theoretical interest since it appears to be provide little evolutionary benefit to the feeding bird.
There were others too — including Dr. A.V. Meigs of Philadelphia, who in 1884 published "the chemical analyses of human and cow's milk that have served as the basis for modern infant feeding ...
