Behaviors performed by parents to increase the survival and reproductive success of their offspring. This includes protection, feeding, teaching, and providing shelter from birth through independence.
From Latin 'parentalis' meaning of parents, combined with 'care' from Old English 'caru' meaning concern or attention. The biological study of parental care developed with the emergence of behavioral ecology in the mid-20th century.
Some animals provide parental care that seems almost supernatural - emperor penguin fathers incubate eggs on their feet for 64 days in -40°C weather without eating! Certain spider mothers actually dissolve their own bodies to feed their spiderlings, the ultimate parental sacrifice.
Early behaviorism assumed maternal care as natural/default; paternal care was framed as deviant or 'unusual.' Language conflated 'parental' with 'maternal'; male investment was rendered invisible or exceptional.
Use 'parental care' and explicitly acknowledge both maternal and paternal investment. Specify which parent(s) provide care and metabolic costs.

Trivers' Parental Investment Theory (1972) revealed investment asymmetries driven by gamete size, not innate sex roles; female care is often greater because of reproductive biology, not maternal instinct.
