 The longhead catshark has no known economic value and as such is not a target of fisheries, though it may be taken as bycatch throughout its range.Even if deepwater fisheries expand, however, the shark would likely to able to elude capture by seeking refuge at greater depths, which is why it has been assessed as Least Concern, even though population data is lacking.Because of its diminutive size and deepwater habitat, it poses no threat to humans.
