TL;DR: This is the first study on a fossil fish otolith assemblage from the Philippines and its diversity is very high and analysis by rarefaction curves suggests that additional sampling would add more fish species to the presented fauna list.
Abstract: We studied fish otoliths from twelve sediment samples of a well-preserved late Pliocene to early Pleistocene fauna originally from the northwest Philippines that were originally deposited in relatively deepwater marine environment. The fish fauna is systematically described, its paleoenvironmental character is explored, and its diversity is analyzed. Four unknown species have been encountered: Parascombrops schwarzhansi n. sp., Maurolicus sp., Pteropsaron sp., and Priolepis sp., of which one is described as new species and three were left in open nomenclature as their local recent counterparts are not well known yet. In addition, a variant Benthosema, Benthosema aff. fibulatum, is described. Overall, fifty-three taxa of fish otoliths were found, of which eighteen were identified at the species level and an additional twenty-seven at the genus level. Most extant species nowadays occur around the Philippines in relatively deep water (about 200 m depth), which is congruent with earlier studies on mollusks and echinoderms from the same deposits. This is the first study on a fossil fish otolith assemblage from the Philippines. Its diversity is very high and analysis by rarefaction curves suggests that additional sampling would add more fish species to the presented fauna list.

TL;DR: Injections and applications of hydrogen peroxide, peroxidase, and other chemicals evoked luminescence with variable success in three Atlantic lanternfishes of the family Myctophidae: Benthosema glaciale, MyCTophum punctatum, and Notoscopelus kroeyeri.

TL;DR: The viper dogfish, Trigonognathus kabeyai is further described on the basis of 19 male and 13 female specimens collected from the Kumano-nada Sea and thought to be a ram feeder.
Abstract: The viper dogfish, Trigonognathus kabeyai is further described on the basis of 19 male [176–470 mm in total length (TL)] and 13 female (325–539 mm TL) specimens collected from the Kumano-nada Sea. In addition, the holotype, paratype, and seven specimens collected from the stomachs of Taractichthys steindachneri and Thunnus obseus from the Ogasawara Islands, Japan, were also examined. This is the first description of large (adult) specimens. The allometric size-on-size equation Y = aX

was used to determine morphometric growth patterns, positive allometry, negative allometry, and isometry. Size at maturity was about 430 mm TL for males and about 520 mm TL for females. Myctophid fishes consisting of Diaphus gigas, Diaphus spp., Benthosema fibulatum, and Benthosema sp. were the only identifiable prey in the stomachs of Trigonognathus kabeyai examined. Most of the prey fishes were found almost intact and usually had puncture holes made by teeth. On the basis of stomach content and jaw morphology, this species is thought to be a ram feeder.

TL;DR: Cluster and distance-based linear model analysis suggested a distinctly structured assemblage of mesopelagic fish larvae was more diverse in winter than in other seasons.
Abstract: This study analyzed the spatiotemporal occurrences of mesopelagic fish larvae in relation to environmental forcing in the Gaoping coastal waters off southwestern Taiwan during August 22–23, 2014 (summer), December 5–6, 2014 (winter), and April 28–29, 2015 (spring). Forty taxa or morphotypes of mesopelagic fish larvae were identified. Skinnycheek Lanternfish Benthosema pterotum (19.1%), Bristlemouth Cyclothone alba (11.6%), Spinycheek Lanternfish B. fibulatum (10.8%), Benthosema spp. (9.4%), and Neoscopelus spp. (9.2%) were the five predominant taxa. Maximum abundance of these taxa generally occurred during the cold period (winter and spring). Although the temporal difference in the abundance of mesopelagic fish larvae was not significant, the assemblage of mesopelagic fish larvae was more diverse in winter than in other seasons. Cluster and distance-based linear model analysis suggested a distinctly structured assemblage of mesopelagic fish larvae. The intrusion of the Kuroshio Branch Current play...

TL;DR: This work describes the presence of widely divergent Benthosema pterotum cryptic species that diverged at least 5 million years ago and its results have important theoretical, as well as practical implications, related to developing mesopelagic fisheries.
