pelagic nudibranchs
Based on the publication titled "the pelagic nudibranch", I assume this was originally the first/only pelagic species known.

One of the other sources mentioned there being five planktonic species. Not sure what was meant at that time... And of course, might be a few yet to be discovered still.. Cesiumfrog (talk) 04:31, 25 January 2013 (UTC)
 * there's two neustonic species (Glaucidae?).
 * this species, and
 * another pair closely related to this one (Phylliroe atlantica & bucephala), these being the three species of the Phylliroidae family.
 * there's some that live crawling upon floating material: Fiona pinnata ("only slightly adapted to pelagic life and resembles in habitus the benthic members of the group" - marine spec. id. portal) or Scyllaea pelagica (the sargassum nudi, which at least "can swim upwards by flexing its body vigorously")
 * but then there's also benthic species that can also swim in bursts, like the spanish dancer.
