We do n’t give snail much credit . They ’re small , worthless , and innocuous for the most part , so unless they ’re munching on our crops , we tend to just have them do their incredibly sluggish matter .
Then there ’s New Zealand’sPowelliphantasnail . The members of this nocturnal and carnivorous genus can grow to the sizing of a person ’s closed fist and – as see in this strikingfilm by BBC Earth – they have a rather striking way of devouring their quarry . mouse up on its unassuming earthworm dinner , it launch its pliant mouth towards it and draws it in with powerful , inescapable sucking .
The crawler test to bunk , but its attack are for naught . In the colored and wet botany - covered landscape , the worm meets its end as all 6,000 of the snail ’s tooth clamp down on it and jaw it into limbo .
The storyteller of the incredible telecasting notes that scientists are not sure exactly how the snail track down their prey .

These hermaphrodite vulture survive for up to 20 days , and spend most of their time hunting down their prey on the timberland base . They are considerably rarified , which is why it ’s assume so long for footage of their dining habits to come about .
Their evolutionary history goes back at least 235 million years , where they originated on the supercontinent of Gondwana . When Australia segregated itself from New Zealand around 80 million years ago , they went along with the latter and have continue there ever since .
They can come in all sorts of color , from red to yellow to black – but back in 2011 , a atomic number 79 - shell , white - bodied albino giant escargot was spotted in Kahurangi National Park .
Their principal predator is the weka , a flightless bird . However , since the reaching of the colonialist in the not - too - distant past tense , their numbers have subdue quite dramatically . enter mammalian predators , particularly rats and possums , have made a huge impingement , and the across-the-board home ground repurposing by James Leonard Farmer and company have importantly shrunk their geographic range .
New Zealand’sDepartment of Conservation(DoC ) draw these gargantuan snail as being “ as representative of New Zealand ’s unique evolutionary history as the kakapo , moa , or apteryx . ” However , it adds that “ despite being legally protect , New Zealand’sPowelliphantaland snails are under serious threat . Several mintage are in danger of extinction . ”
In fact , the DoC has considered the plight of these massive snails to be serious enough to warrant some rather drastic mitigation bill .
In the last two decades , aery poison dispersions on a truly massive scale leaf have been transmit so as to pick the rising routine of mammals . The data seems to show that it has worked to some degree , with snail number on the rise – but dumping poison from the sky is a somewhat imprecise and jeopardy - prone method .
