this individual,,most similar to,,Eurypleuron owasianum (Matsubara 1953) ソコカクレウオ

",,, an ophidiiform larva with an ovoid body, elongate anterior dorsal-fin ray,
and long trailing fleshy filament has been identified as Pycnocraspedum squamipinne.
Similarly, the larvae of the ophidiid genus Luciobrotula have been tentatively identified since 1988,
with posteriorly displaced dorsal fins and bulging or exterilium guts.
However, neither of these larval forms morphologically agree with their adult counterparts.
,,,Our study emphasizes the importance of blackwater diving to improving our understanding of marine larval fishes
and the need for additional molecular sampling of the diverse order of brotulas, cusk-eels, pearlfishes, and their allies."
