Carnivorous mound plants are pretty badass as botanic beasts go ( someeat fire hook , ‘nuff said ) , and they just got a whole heap more metal as for the first time scientists have expose a nepenthes species that feasts underground . The subterraneous piranha was found in North Kalimantan , Indonesia , where it catch ants and other insects in mound that acquire in grease cavum .
The first - of - its - form mintage has been describe inPhytoKeysand namedNepenthes pudicaby the team who traveled to North Kalimantan ’s montane rain forest back in 2012 . Here , they find that beneath the surface of the earth , N. pudicawas employing a pin down strategy never before examine in carnivorous plant .
immobilize living quarry underground is n’t unheard of among the leafy meat - eaters , but other plants that do this use dissimilar trap styles , such asUtricularia ’s sucking utricles , to the sticky leaves ofPhilcoxiaand the lobster - pot approach path ofGenlisea . Instead , N. pudicagrows well - develop , fully - functional pitcher traps

The traps produce almost entirely onN. pudica ’s belowground basal shoot and measure around 7–11 centimeters high and 3–5.5 centimeter widely . A small meal for a human , but that ’s great deal of place for make up some ant mallet broth .
The carnivore appears to favour tree diagram whose branch ancestor have formed cavity that are topped with a moss stratum , make plenty of infinite for them to unfurl their predatory pitchers . If space is in short provision , N. pudicawill also grow hurler in soil or under moss cushions .
When they seem at other Nepenthes species in the area , they distinguish thatN. pudicawas the only plant sprouting pitchers underground . This is interesting , as it demonstrate that the trait is n’t simply a result of the plant ’s environment but seemingly an adaptative behaviour germinate by this species specifically .
“ The undercover shoots ofN. pudicahad no obstacles preclude them from growing upwards , ” write the study authors . “ Neither did they show mansion of growing towards Christ Within , even when concealed only under a soft moss cushion . ”
Beyond enticing alternative for afilm sequelLittle Shop of Horrors : This Time It ’s Earthy , the discovery of a new feeding strategy among carnivorous plant in Borneo exhibit the scientific value of the region , say the researchers , and the necessity to protect it .
“ Nepenthes pudicais known only from a few neighbouring locality in the Mentarang Hulu district of North Kalimantan , where it maturate on ridgetops at an elevation of 1100–1300 [ meters ] , ” they write . “ Its find emphasise the natural grandness of Borneo ’s rain forest and the essential to preserve this crucial ecosystem with its enormous and still undiscovered biodiversity . ”
