鼠尾鱈科 (Grenadiers or rattails)
Etymology: Hymenocephalus: Named for its transparent membrane-like head covering (‘‘hymen head’’) and fragile nature of head bones (Ref. 100825).
Eponymy: In Greek mythology, Nesaie was one of the Nereids, a sea nymph. The junior author later commented there is no particular allusion or meaning, simply: “…a nice name that might have some bearing on the creature.” (Ref. 128868), visit book page.
