In a humans first , scientist have filmed a rare carnivorous snail place an orchis from a " genital pore " in its neck .
The footage answers long - standing interrogative about how the mysterious mollusc — know as the Mount Augustus snail ( Powelliphanta augusta ) — reproduce .
Like many snails,Powelliphantaare hermaphrodites, meaning they have both male and female reproductive organs.
" It ’s remarkable that in all the clip we ’ve spent caring for the snails , this is the first time we ’ve see one lay an egg , " Lisa Flanagan , a New Zealand Department of Conservation ( DOC ) ranger who captured the footage , said in astatement . " We caught the natural process when we were weighing the snail . We turn it over to be weighed and saw the egg just starting to emerge from the escargot . "
In the video , a single pearly livid egg oozes out of the snail ’s slimy neck folds , from an possible action known as a genital stomate .
There are at least 20 species and 59 sub - species ofPowelliphantasnails , and they are among the bombastic snails in the world , according to theDOC.Powelliphantasnails are nocturnal and seldom number out during the twenty-four hours , except when it is particularly rainy . Therefore , they are not often very rarely blob by humankind .
They are also among New Zealand ’s most threatened invertebrate species due to depredation and habitat loss .
According to the DOC , P. capital of Maine , only found on the Buller Plateau on New Zealand ’s West Coast , are threatened by quenching due to clear - cast coal mining in their aboriginal range .
Because of their shrinking population and nocturnal demeanor , very slight is sleep together about these fauna ' life Hz and behavior . Therefore , wildlife officials have been study a population in captivity for nearly 20 year .
" DOC has been managing this captive population in cool containers in Hokitika since 2006 , when work began to mine the legal age of their home ground on the West Coast of the South Island , " the DOC representatives said in aFacebook post . " Very little was know about the species before they were take into captivity . "
Like many snails , Powelliphantaare hermaphrodite , signify they have both male and female reproductive pipe organ . P. augustaare long - live and obtuse to age , only contact sexual maturity at around 8 age old — which is very sure-enough for a snail . Mature snails normally lay around five eggs a twelvemonth , which can take more than a year to think up .
" Some of our absorbed snail are between 25 and 30 years one-time — in this they ’re polar opposites to the pest garden snail we introduced to New Zealand which is like a weed , with grand of issue each year and a short liveliness , " Kath Walker , DOC senior science consultant , said in the statement .
While the snails ' hard shells serve to protect them from depredation and rough conditions , they also make it difficult to get sperm cell from one escargot into another . " Powelliphantahave solved this by having an gap ( a genital pore ) on the right side of their torso just below their head so that the snail only needs to glint out of its shell to do the business , " Walker said .
" It extends its penis out of this pore and into its mate ’s pore , and its mate does the same , simultaneously exchanging sperm , which they can store until they each feed the sperm cell they ’ve received to create orchis , " Walker said .
She bring that , because they have both male and female reproductive variety meat , the snails can also self - fertilize .

lay eggs through a genital stomate is common among escargot specie , although some coinage , such asLittorina saxatilisin the U.K. , give birth to experience new . ButPowelliphantaspecies are strange because they only lay one egg at a time , rather than the big eggy cluster produced by many other more common snail species , according tothe Carnegie Museum of Natural History .
To save these alien snails , the DOC has established new populations in the wild by introduce them into new and rehabilitated habitats . However , they will continue to manage populations in incarceration too until they are confident that the species is survive well in the wild .
" The captive direction ofPowelliphanta augustahas not only saved the mintage from extinguishing , but it ’s allowed us to learn more about the lives of these incredible creatures found nowhere else in the macrocosm , " according to the statement .
