Cichlid. In addition to being mouthbrooders, some species continue to protect their young after they hatch, calling out to them when there is danger, and letting them swim back into their mouth to hold them safely away. [1] Apogonidae. Ariidae males carry a clutch of a few dozen eggs in their mouths, [2] for about two months before they hatch.
Swallow adult feeding begging young in the nest. Parental care is a behavioural and evolutionary strategy adopted by some animals, involving a parental investment being made to the evolutionary fitness of offspring. Patterns of parental care are widespread and highly diverse across the animal kingdom. [1] There is great variation in different ...
Infanticide (zoology) Lion cubs may be killed by males replacing other males in the pride. [1] In animals, infanticide involves the intentional killing of young offspring by a mature animal of the same species. [2] Animal infanticide is studied in zoology, specifically in the field of ethology. Ovicide is the analogous destruction of eggs.
Precociality and altriciality. Precocial species in birds and mammals are those in which the young are relatively mature and mobile from the moment of birth or hatching. They are normally nidifugous, meaning that they leave the nest shortly after birth or hatching. Altricial species are those in which the young are underdeveloped at the time of ...
Alloparenting (or alloparental care) is a term for any form of parental care provided by an individual towards young that are not its own direct offspring. These are often called "non-descendant" young, [1] even though grandchildren can be among them. [2] Among humans, alloparenting is often performed by a child's grandparents and older ...
Parental care refers to the level of investment provided by the mother and the father to ensure development and survival of their offspring. In most birds, parents invest profoundly in their offspring as a mutual effort, making a majority of them socially monogamous for the duration of the breeding season. This happens regardless of whether ...
Prairie dog burrows contain chambers to provide certain functions. They have nursery chambers for their young, chambers for night, and chambers for the winter. They also contain air chambers that may function to protect the burrow from flooding [19] and a listening post for predators.
A nest is a structure built for certain animals to hold eggs or young. Although nests are most closely associated with birds, members of all classes of vertebrates and some invertebrates construct nests. They may be composed of organic material such as twigs, grass, and leaves, or may be a simple depression in the ground, or a hole in a rock ...
