1rst is possibly Bolinopsis
1rst is possibly Bolinopsis indonensis (Dawydoff 1946) by the aboral protuberances (almost keels), the simplicity of the lobe canal system and the relative size of the auricles. The spotted pigmentation around the stomodaeum is not described, but could be a new specific trait (or a new species close to B. indonensis). Probably an adaptation to hide bioluminescent prey.
2nd Bolinopsis has this 4 spots at the end of what appears to be the subtentacular meridional canals. Cannot see the aboral side so impossible to fully identify. The hitchiking amphipods resemble those from the Oxycephalidae family, maybe Glossocephalus.
The Ocyropsis could be O. brune (a.k.a. fusca) mostly beacuse the distribution range (O. crystallina is not known to live in the western Pacific). Traits against O. maculata: spots not visible, eccentrity of the hourglass shape of the stomodaeum is moderate.
Didnt find any of the 'Dawydoff aberrations' in those waters? maybe they should be regarded as cryptozoology already!
