Question

what are the parental care with examples

Answer 1

It may also include the cooperative rearing of offspring by the parents. Parental care refers to any behaviors on the part of either or both parents that help their offspring survive. In many birds, parental care includes building a nest and feeding the young.

Answer 2

Parental care is a behavioural and evolutionary strategy adopted by some animals, making a parental investments into the revolutionary fitness of their offspring. This strategy means that more effort is spent on a relatively small number of offspring to give each of them a high chance of surviving to reproduce; an opposite strategy is to produce a very large number of small offspring, often as eggs, which are left to fend for themselves.Parental care is apparently absent in the jawless fishes and cartilaginous fishes, but the bony fishes (teleosts) exhibit the same diverse array of parental carepatterns as seen in birds, including brood parasitism, in which eggs are deposited in the nests of a host species. Unlike birds, however, exclusive parental care by the male is the most common pattern and is seen in over 50% of teleost families. It is also the pattern that has been studied most extensively by behavioral endocrinologists. Many teleost species also differ from avian species in exhibiting striking polymorphisms in male size and mating strategy, with only the large nesting males exhibiting parental behavior. The most common components of male parental care are nest building or substrate clearing, aeration of eggs by fanning, and guarding of eggs from brood predators, although other adaptations, such as mouthbrooding, are also displayed in some species. Parental care in most male teleosts ends at the time of hatching, although continued care of the newly hatched fry occurs in some species.
