487: 610:). Because they inhabit deep-waters and because of their low commercial value the effort put into data collection is low, as with many species under these circumstances. Although their appearances are fragmented they still are classified under large broader spaces due to the lack of research done. As a result, ranges of deep-water shark species are often considered continuous across broad expanses despite records of occurrence, in many cases, being spatially fragmented.
