This species is found from Morocco southward through Gabon with records in North Ireland to Mediterranean Sea. It occurs at depths greater than 1,000 m. This species is not utilized and given its general depth range it is not likely to be affected by anthropogenic disturbances. It is therefore listed as Least Concern.
|Range Description:||Bathysaurus mollis is circumglobal between 50°N and 20°S, except in the tropical eastern Pacific. In the eastern Atlantic, it is present in North Ireland to Morocco and south to Gabon. In the Mediterranean Sea, there is only one single record (Whitehead et al. 1986) in the northwest part of the basin. It occurs at depths greater than 1,000 m.|

|Population:||There are very few collection records in museums. There is very little information on the population of this species in western Africa and only one record from the Mediterranean Sea.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Bathysaurus mollis is a bathydemersal species with a maximum size of 78 cm. It is found on the continental rise and the abyss, commonly below 2,000 m, in water colder than 4°C. Larvae are pelagic in near-surface midwaters. It is a solitary, lurking bottom feeder, probably piscivorous (Sulak 1984). Contrary to Thresher (1984) this species is a hermaphrodite (Nelson 1994). Species of the family Synodontidae usually eat other small fish and crustaceans (Russell in press).|
|Use and Trade:||There is currently no information regarding the use and/or trade of Bathysaurus mollis. This species is likely too deep-dwelling to be consumed in western Africa.|
|Major Threat(s):||There are currently no known threats to Bathysaurus mollis and because of the depth distribution of this species, it is less likely to be threatened by anthropogenic disturbances.|
|Conservation Actions:||There are no species-specific conservation measures in place for Bathysaurus mollis. It may be present in marine protected areas that occur within its distribution.|
