The mammalian pseudo-penis appears to be simply for display, though the spotted hyena is an exception: the female spotted hyena urinates, copulates, and gives birth through her pseudo-penis. This prevents males from mating without the full co-operation of females, which means that mating preferences of the female are predominant.
Sequential hermaphroditism is very rare and according to scientists this is due to some cost that decreases fitness in sex changers as opposed to those who do not change sex. Some of the hypotheses proposed for the dearth of hermaphrodites are the energetic cost of sex change, genetic and/or physiological barriers to sex change, and sex ...
Hyenas do not regurgitate food for their young and male spotted hyenas play no part in raising their cubs, [44] though male striped hyenas do so. [51] The striped hyena is primarily a scavenger, though it will also attack and kill any animals it can overcome, [45] and will supplement its diet with fruit. [52]
Sexual mimicry can play a role in the development of a species' social system. Perhaps the most extreme example of this can be seen in the spotted hyena, Crocuta crocuta. [1] Female hyenas of all ages possess pseudomasculinized genitalia, including a pseudopenis formed from the clitoris, and a false scrotum formed from the labia.
“The sex characteristics a person is born with do not signify a person's gender identity,” adds Golob. “When people have ‘gender reveal parties,’ it really should be called a ‘genital ...
The spotted hyena (Crocuta crocuta), also known as the laughing hyena, [3] is a hyena species, currently classed as the sole extant member of the genus Crocuta, native to sub-Saharan Africa. It is listed as being of least concern by the IUCN due to its widespread range and large numbers estimated between 27,000 and 47,000 individuals. [1]
Florida will no longer allow transgender people to change the sex on their state driver’s license to reflect their gender identity, a policy change that muddles whether trans people who have ...
Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals.
