Because these individual were not collected, it is not possible to obtain species-level identifications. However, these sightings likely exceed the deepest known records for genus "Peniagone" and family "Munnopsidae".

The oceanic trench is associated with a complex transition between the Lesser Antilles subduction zone to the south and
