Fellatio hos fladdermöss, mentala sjukdomstillstånd kopplat till arbete hos hästar

Rykande färska nyheter från de biologiska vetenskaperna. Kinesiska forskare rapporterar i veckan att de funnit fellatio hos Cynopterus sphinx (indisk kortnosad flyghund) – en stor fladdermus. Sammanfattningen, på saklig forskarprosa (som sig bör) lyder som följer:

Oral sex is widely used in human foreplay, but rarely documented in other animals. Fellatio has been recorded in bonobos Pan paniscus, but even then functions largely as play behaviour among juvenile males. The short-nosed fruit bat Cynopterus sphinx exhibits resource defence polygyny and one sexually active male often roosts with groups of females in tents made from leaves. Female bats often lick their mate’s penis during dorsoventral copulation. The female lowers her head to lick the shaft or the base of the male’s penis but does not lick the glans penis which has already penetrated the vagina. Males never withdrew their penis when it was licked by the mating partner. A positive relationship exists between the length of time that the female licked the male’s penis during copulation and the duration of copulation. Furthermore, mating pairs spent significantly more time in copulation if the female licked her mate’s penis than if fellatio was absent. Males also show postcopulatory genital grooming after intromission. At present, we do not know why genital licking occurs, and we present four non-mutually exclusive hypotheses that may explain the function of fellatio in C. sphinx.

Har någon påstått att forskning är osexigt? För den som tänder till och vill veta mer finns hela rapporten för allmän läsning hos tidskriften PLoS ONE.

I samma tidskrift rapporterar en annan forskargrupp att de funnit en koppling mellan mentala sjukdomstillstånd (stereotypier) och vilken typ av arbete som hästarna utför. Värst var situationen för dressyrhästar.

Ni får dra era egna slutsatser av den sistnämnda studien.
