Distribution
editThis species is found only around New Zealand, although its 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
editThe New Zealand Department of Conservation has classified the flaccid catshark as "Data deficient" under the New Zealand Threat Classification System.[4]
