Elephants live in large or small herds that can range in size from less than a dozen to over members. Females and their young form the nucleus of a herd, which is usually led by a senior matriarch. The matriarch is usually of about 30 or 40 years of age.

Permuted discriminant function analysis revealed that rumbles contain sufficient acoustic information to predict the sex of a vocalizing individual. Yet, controlling for age and size effects, our results indicate that the pronounced sexual size dimorphism in African elephants is partlybut not exclusivelyresponsible for sexual differences in social rumbles. This provides a scientific foundation for future work investigating the perceptual and functional relevance of specific acoustic characteristics in African elephant vocal sexual communication.

They also have straighter, thinner tusks, more rounded ears and differently shaped skulls. Both elephant species exhibit sexual dimorphism, where males are larger than females, with wider-set tusks, more rounded foreheads and less curvature in their spines. Reproductive rates for both species are considered one of the slowest and most energy-intensive.

Testosterone levels in an elephant in musth can be on average 60 times greater than in the same elephant at other times in specific individuals these testosterone levels can even reach as much as times the normal. Scientific investigation of musth is problematic because even the most placid elephants become highly violent toward humans and other elephants during musth. Although it has often been speculated by zoo visitors [2] that musth is linked to rutit is unlikely there is a biological connection because the female elephant's estrus cycle is not seasonally-linked, whereas musth most often takes place in winter.

Existing neurodevelopmental models have integrated our current understanding of adolescent brain development; however, there has been surprisingly little focus on the importance of adolescence as a sensitive period for romantic and sexual development. As young people enter adolescence, one of their primary tasks is to gain knowledge and experience that will allow them to take on the social roles of adults, including engaging in romantic and sexual relationships. By reviewing the relevant human and animal neurodevelopmental literature, this paper highlights how we should move beyond thinking of puberty as simply a set of somatic changes that are critical for physical reproductive maturation.

Males are found with female herds when one or more females is in oestrus. Males will breed with females whether or not the males are in musth. The male may touch the female's vulva with his trunk tip then raise his trunk to his mouth, possibly conveying the scent to Jacobson's organ. Before mating, the elephants may stand head-to head, touching mouths and intertwining trunks, or circle, touching one another's genital areas.
