Gray wolves are the largest wild dog species in the world. They vary in size depending on where they are found, with southern populations being generally smaller than northern populations. Total body length, from tip of the nose to tip of the tail, is from to 1, mm. Height measured from base of paws to shoulder generally ranges from 60 to 90 cm. Males are, on average, larger than females. Fur color of gray wolves also varies depending on where they are living.

sexual dimorphism | Definition, Examples, & Facts | Britannica

Sexual dimorphism , the differences in appearance between males and females of the same species , such as in colour, shape, size, and structure, that are caused by the inheritance of one or the other sexual pattern in the genetic material. The differences may be extreme, as in the adaptations for sexual selection seen in the exotic plumes and colours of the male bird-of-paradise family Paradisaeidae or in the adaptations for protection exemplified by the great size and huge canine teeth of the male baboon Papio. Many birds show at least some dimorphism in colour, the female being cryptically coloured to remain concealed on the nest while the more-colourful male uses display in courtship and territorial behaviours. The mountain spiny lizard Sceloporus jarrovi is sexually dimorphic in feeding habits: the equal-sized males and females seek out different sizes of prey. Pronounced size differences may occur between the sexes.

Examples of Sexual Dimorphism in Animals

Procreation through sexual reproduction implies the necessary presence of two different sexes. The competition for resources, the risk of predation, the energy expenditure of finding and courting a mate have made many animal species evolve to facilitate this entire process. In this AnimalWised article we will define sexual dimorphism, explain what causes this condition and give examples of sexual dimorphism with photos. Continue reading to learn more! Sexual dimorphism is when the two sexes of the same species exhibit different characteristics beyond the differences of their sexual organs.

Microglia participate in synapse remodeling in the cortex and hippocampus during mouse postnatal development. Although sex differences in microglia activity during embryonic development have been reported in these regions, it remains unexplored whether microglia show sexually dimorphic features during the early postnatal period, a critical window for synapse formation and maturation. Here, we investigated morphological and functional features of microglia across early postnatal development as well as morphological features of both pre- and postsynaptic neuronal compartments in the mouse hippocampus.
