“…The Giant Grenadier exhibits a typical form of "rattail, " i.e., the caudal area is narrowed to the posterior point. The swimming speed of the Giant Grenadier was presumed to be slow (Rodgveller et al, 2017), and individuals could be caught by trawling (Napazakov and Chuchukalo, 2011;Hutchinson and Anderl, 2012). In contrast, the Yokozuna Slickhead is fusiform and has a narrowed but robust caudal peduncle with a relatively large emarginate caudal fin (Fujiwara et al, 2021a).…”

The Yokozuna Slickhead Narcetes shonanmaruae is a recently described deep-sea fish species and an active-swimming, relatively large top predator in Suruga Bay, Japan. Its only known habitat is the deepest part of the bay (>2,000 m); six individuals have been collected thus far (up to 138 cm in total length). During our monitoring survey of faunal diversity on seamounts within marine protected areas in Japanese waters, environmental DNA (eDNA) metabarcoding revealed the Yokozuna Slickhead 12S ribosomal RNA gene sequence on/around three seamounts belonging to the Nishi-Shichito Ridge (at depths of around 2,000 m) located 400–600 km south of the known locality. A baited camera system deployed at the foot of one of the three seamounts at a depth of 2,091 m captured a Yokozuna Slickhead individual that was over 250 cm in total length, threatening Pacific Grenadiers Coryphaenoides acrolepis around the bait and attacking the bait cage. A combination of eDNA metabarcoding and baited camera observation represents a powerful tool for the detection of rare predatory fish species and the study of their ecology even in the deep sea, thus helping to better understand vulnerable marine ecosystems and reveal the impact of the rapidly changing global ocean.

Genetic and morphological analyses were used to revise historical controversies in identities of Beroe species in the southern seas of Europe. DNA analyses with ITS sequences were used to explore their phylogenetic relationships. Three species of Beroe were initially listed as occurring in the Mediterranean Sea. Recently, the specimens were often re-identified using genetic analyses, causing confusions of identity. In 1997, a non-native Beroe was introduced into the Black Sea, which established there and spread to the adjacent seas, adding more controversy and confusion to species identification in this group of comb jellies. Our revisions suggest the following systematic changes: (1) re-naming of the species from what was initially labelled as Beroe ovata, and later as B. cucumis (sensuMayer, 1912), to Beroe pseudocucumis sp. nov.. (2) Beroe mitrata but not Beroe ‘anatoliensis’ inhabits the Aegean Sea, as was reported previously. (3) Beroe ovata is the only species of Beroidae that became invasive and should be used with the authority of Bruguière, 1789, but not in the sense of Mayer, 1912. (4) Beroe forskalii appears to be represented by two species in the Mediterranean and in the Antarctic, but further justification is needed. (5) Beroe cucumis is a species of bipolar occurrence, inhabiting both subpolar areas and its recent definition as Beroe ‘norvegica’ is incorrect.
