Parabrotula Tanseimaru
''Parabrotula tanseimaru'' is a species of ray-finned fish within the family Parabrotulidae, that is found off southern Japan in the Sagami Bay. It is a bathypelagic species, swimming at depths up to 1300 meters below sea level. It feeds on copepods and grows to around 4.9 centimers in length, with the largest specimen being 6.2 centimeters in length. The species is only known from a single type locality collected off Sagami Bay, with 25 other specimens being caught in trawl nets up to 680 meters deep. The species has been classified as 'Data deficient A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessaril ...' by the IUCN Red List, as its current population is unknown, and no conversation efforts have been made towards it.

Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinopt ...
