Nessorhamphus danae has been assessed as Least Concern. Due to the deep-water nature of this wide-ranging species, it is unlikely to be impacted by any major threat processes. However, further research on the ecology of this species is needed so that any potential threat processes can be identified.
|Range Description:||Nessorhamphus danae is found in tropical waters in the western Pacific, Indian, and Atlantic Oceans.|

|Population:||It is likely that Nessorhamphus danae occurs at very low densities of around 1 individual per 1,000–10,000m3(T. Clarke pers. comm. 2008). This species is only known from a relatively small number of occurrences.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Nessorhamphus danae is a bathypelagic species and has been found in both oceanic areas and on the continental shelf. The Derichthyidae family inhabits waters several hundred metres deep and specimens are rarely seen.|
|Major Threat(s):||Due to the deep-water nature of this species, it is unlikely that Nessorhamphus danae is being impacted by any major threat processes. There is no known commercial fishery for this species.|
There are no species-specific conservation measures in place for Nessorhamphus danae.
Further research is needed on the ecology of this species, in order to better understand any potential threats it may face.
