About 30% of the 500 known fish families show some form of parental care, and most often (78% of the time) care is provided by only one parent (usually the male). Male care (50%) is much more common than female care (30%) with biparental care accounting for about 20%, although a more recent comparative analysis suggests that male care may be ...
Mouthbrooding is the care given by some groups of fish (and a few other animals such as Darwin's frog) to their offspring by holding them in their mouth for extended periods of time. Mouthbrooding has evolved independently in several different families of fish including the cardinalfish , sea catfish , bagrid catfish , cichlids , snakeheads ...
[1] [15] Many cichlid species, such as Cichla ocellaris, will also remove underdeveloped eggs from the clutch, a behavior performed by both parents. [15] Many female cichlids also fan their eggs with their fins, especially in slower moving water, in order to increase oxygenation and get rid of build up of undesired materials around the eggs. [15]
Scientists have debated whether humans are prosocial or eusocial. [45] Edward O. Wilson called humans eusocial apes, arguing for similarities to ants, and observing that early hominins cooperated to rear their children while other members of the same group hunted and foraged. [46]
Altricial young are born helpless and require care for a length of time. Altricial birds include hawks, herons, woodpeckers, owls, cuckoos and most passerines. Among mammals, marsupials and most rodents are altricial. Domestic cats, dogs, and primates, such as humans, are some of the best-known altricial organisms. [14]
Alloparental care has many benefits for the young as well as the biological parents of the young. It occurs when there is a high energetic command of the biological parents and the group living of these animals. [4] Alloparenting helps to reduce the stresses on these animals and reduce the overall energetic demands of having offspring. [4]
"The problem with floaties is that it gives parents a literal false sense of security," Gaines, a member of the the P o o l & Hot Tub Alliance (PHTA), a nonprofit organization that promotes ...
Some species gather up fertilized eggs in their mouth and keep them safe until they hatch, a process called mouthbrooding. 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.
