Etymology The species epithet shonanmaruae is a feminine noun in Latin, referring to the ship ‘Shonan maru’ from which the type materials were caught, honouring the vessel’s considerable contribution to deep-sea fish research in the area. The proposed Japanese vernacular name is ‘Yokozuna Iwashi’. This species belongs to the family Alepocephalidae, which is referred to as ‘Sekitori Iwashi’ in Japanese: ‘Sekitori’ meaning a sumo wrestler and ‘Iwashi’ meaning a sardine, thereby implying a massive sardine. The term ‘Yokozuna’ refers to the highest rank in sumo wrestling in Japan. Accordingly, we propose the name ‘Yokozuna Iwashi’ as being indicative of the large body size and the high trophic position of the newly described species. English vernacular name: Yokozuna Slickhead. [details]
