Distribution

This species is found only around New Zealand, although this species' collection records indicate it is widespread and probably continuously distributed over the mid- to lower slope around New Zealand.[2]:80 The biology of all Apristurus species within the New Zealand Exclusive Economic Zone is very poorly known due to the uncertain taxonomy of the group.[2]:75 They appear to be most abundant below 1,000 m, and are the only sharks regularly taken in research trawls below 1,200 m on the Chatham Rise.[2]:80 As relatively little fishing occurs below 1,200 m, a large part of their population may be effectively beyond fishing depths.[3]

Conservation status

The New Zealand Department of Conservation has classified the flaccid catshark as "Data deficient" under the New Zealand Threat Classification System.[4]

gollark: Well, that means potatOS can (theoretically, I haven't implemented code for it) edit your world, so... yay?
gollark: You should run it, though.
gollark: As I said, I cannot neither antideny nor unconfirm that potatOS won't not spread to no disks.
gollark: And?
gollark: Anyway, I cannot neither unconfirm nor antideny that potatOS may or may not spread to no disks across networks.
