Environnement : milieu / zone climatique / profondeur / gamme de distribution
Écologie
marin pelagic-oceanic; océanodrome (Ref. 51243). Subtropical
Central Atlantic: Southwards to South Africa in the eastern part. Records outside central western Atlantic should be different species (H.Ho, pers.comm. 2/2017).
All reports in the Mediterranean Sea before 2017 are misidentifications for Bregmaceros nectabanus Whitley, 1941.
