Sexual dimorphism in birds can be manifested in size or plumage differences between the sexes. Andrena agilissima is a mining bee where the females only have a slightly larger head than the males. In other cases with fish, males will go through noticeable changes in body size, and females will go through morphological changes that can only be seen inside of the body. Some such plants go even further and change their appearance again once they have been fertilised, thereby discouraging further visits from pollinators. In addition the males do not provide parental care for the young and allocate more energy to growth. There is aggressive competition by males over territory and access to larger shells.

The female's small body size is also likely beneficial to her chances of finding an unoccupied shell. Social organization plays a large role in the changing of sex by the fish. In some species, the male's contribution to reproduction ends at copulation, while in other species the male becomes the main caregiver. For instance, the average male Anolis sagrei was However, selection for ornamentation within this species suggests that showy female traits can be selected through either female-female competition or male mate choice. This is advantageous to both parties because it avoids damage to the developing fruit and avoids wasting the pollinator's effort on unrewarding visits. The male's increased size is believed to be advantageous because males collect and defend empty snail shells in each of which a female breeds. This balance keeps the dimorphism alive in these species and ensures that the next generation of successful males will also display these traits that are attractive to the females. For example, in the blue-footed booby , the female chicks grow faster than the males, resulting in booby parents producing the smaller sex, the males, during times of food shortage. If these are the result for every migration and breeding season the expected results should be a shift towards a larger male population through sexual selection. Females of the aquatic plant Vallisneria americana have floating flowers attached by a long flower stalk that are fertilized if they contact one of the thousands of free floating flowers released by a male. It has been shown that the larger males are better at coping with the difficulties of migration and thusly are more successful in reproducing when reaching the breeding destination. The males of these species will molt into a less bright or less exaggerated color during the off breeding season. Sexual dimorphism is maintained by the counteracting pressures of natural selection and sexual selection. Sexual dimorphism also occurs in hermaphroditic fish. This then allows for females to be larger in his brooding nest which makes the difference between the sizes of the sexes less substantial. Some plants, such as some species of Geranium have what amounts to serial sexual dimorphism. Larger shells, although preferred by females, are often limited in availability. However, sexual dimorphism is not only found in birds and is thus important to the conservation of many animals. These species are known as sequential hermaphrodites. This means that even if the trait causes males to die earlier, the trait is still beneficial so long as males with the trait produce more offspring than males lacking the trait. Pinnipeds are known for early differential growth and maternal investment since the only nutrients for newborn pups is the milk provided by the mother. Some such plants go even further and change their appearance again once they have been fertilised, thereby discouraging further visits from pollinators. When the environment gives advantages and disadvantages of this sort, the strength of selection is weakened and the environmental forces are given greater morphological weight. Male coloration appears to reflect innate anti-oxidation capacity that protects against oxidative DNA damage. Sexual dimorphism is a product of both genetics and environmental factors. An example of sexual polymorphism determined by environmental conditions exists in the red-backed fairywren.

  1. In fish, reproductive histories often include the sex-change from female to male where there is a strong connection between growth, the sex of an individual, and the mating system it operates within. This can be seen in Cannabis sativa , a type of hemp, which have higher photosynthesis rates in males while growing but higher rates in females once the plants become sexually mature.

  2. The bees will then avoid other male flowers but may visit the female, which looks different from the males. Male Catasetum orchids violently attach pollinia to euglossine bee pollinators.
