Habitat

This snail has been found in two caves in very close proximity within a 1 km² area in Pohara, Takaka . The population trend of this snail is unknown at present but it is regarded as potentially threatened by urban development and groundwater removal and contamination.[3]

Conservation status

In November 2018 the Department of Conservation classified Opacuincola dulcinella as Nationally Critical under the New Zealand Threat Classification System.[1] The species was judged as meeting the criteria for Nationally Critical threat status as a result of it occupying a total area of less than 1 hectare. It is found in what is regarded as one location and is also classified as Data Poor under the threat classification system.[1]

gollark: Not that I'd have much idea regarding making an improvement, but they emulate ancient CPUs in order to run C and C-style code, and are slow/buggy/exploitable because of it.
gollark: Modern CPUs are kind of awful anyway.
gollark: Good idea.
gollark: Still, open-sourcing a few things is a start.
gollark: True, true; the whole thing is a fiendishly complex multi-layer system, and much of it never will be.
