The morphological and genetic lines of evidence that distinguish these whales in the GOMx as a new species also provide equivalent support for re-elevating the two subspecies of <i>B. edeni</i> to species level, <i>B. edeni</i> and <i>B. brydei</i>. According to AMS (2025), \"this taxonomic arrangement has not been accepted by some researchers given that there is ongoing nomenclatural controversy associated with the holotype of <i>B. brydei</i> and discussion over whether the three should be considered distinct species or subspecies.

Minimally, at least two and preferably several years of observation should be used to reliably identify significant concentrations (i.e., those occupied by feeding whales more than 10 days per year). In most cases, occurrences should not be extensive areas, but rather portions of such areas that stand out as strongly meeting the occurrence criteria. Year-to-year changes in prey distribution may mean that some key sites are not occupied every year; however, occurrences should still be delineated where data indicate that the sites are important over the longer term.","mappingGuidance":"All known sightings over a period of time in an area should be collectively mapped as a single polygon feature, or multiple polygons if there are individual areas separated by more than 5 km. Individual sightings could also be mapped as source feature points within this principal EO, although this may be impractical over time. If useful, year-to-year variation in areas could be mapped as separate source feature polygons within a larger multi-year principal EO.","separationBarriers":"None.","separationDistanceUnsuitableHabitatat":30.0,"separationDistanceSuitableHabitatat":30.0,"altSeparationProcedure":null,"separationJustification":"Whales can travel significant distances daily.
