dolphinfish crotch , the final frontier . skill knows very little about marine mammal sex activity , especially when it comes tofemale reproductive organsinvolved . Since it ’s so tricky to mention maritime mammals get down and dirty in the wild , or even in an marine museum , how would you go about canvas this ?
Well , this team of scientists from Dalhousie University lead byDara Orbachknows how . Their novel method involve amplify the phallus of the beat marine mammals with saline to mimic an hard-on . They then inclose this stiff phallus inside comparable vagina , and apply CT scans to see what on the nose is going on in there . All the specimen were find in the US and conk out of natural causes .
The team presentedtheir preliminary findingsa few months ago but now their study , Genital interaction during simulated copulation among marine mammal , has been published in the journalProceedings of the Royal Society Bin all its glory .
In their late study , they employed their revolutionary proficiency on four metal money of marine mammal : bottlenose dolphins , rough-cut dolphin , harbor porpoises , and harbor seals .
Their determination shew that the biomechanics of nautical mammal sex activity is in reality somewhat complicated .
“ Whales , dolphins , and porpoises have unusual vaginal folds , helix , and recesses that the penis and sperm must voyage through to successfully inseminate the bollock , " Orbachexplainedat the American Association of Anatomists one-year get together in April 2017 .
This is encounter to be peculiarly true with harbor porpoises and common bottlenose dolphins , where researchers find the phallus and vagina were an " antagonistic burst , " as the female vaginal fold appear to pretend as a barrier to penial incursion . These construction and turn actually make it harder for the spermatozoan to meet the testis , meaning the female can curb which Male are able to fertilize her ballock . This means only the dear mates with the “ strong ” gene are selected .
The survey also excuse another vantage to these rather strange vaginas : “ In plus , the folds may serve as a mechanism to forbid seawater from entering the female reproductive tract , as seawater is lethal to sperm in at least one mintage of blower . ”
The learning does n’t block up there . The researcher also trust these breakthrough will be used to produce better biomimetic vaginas that are capable of gathering a high volume of ejaculate from males during semen assembling procedures .
