Dolichostomus leucotaenia gen. et sp. nov. is described from two specimens collected from off northern Vietnam. It is characterized by a long, oval mouth opening visible from the ventral view, a feature unique among the order Myxiniformes. It also possesses a single medial nasal‐sinus papilla and branchial slime pores positioned external to the gill‐aperture series. Moreover, it can be further distinguished by its slender body...

Viral hemorrhagic septicemia virus (VHSV) is a highly pathogenic rhabdovirus that primarily spreads through horizontal transmission. Characterizing viral shedding dynamics is therefore critical for understanding its epidemiology and improving disease control strategies in aquaculture. In this study, the median lethal dose (LD₅₀) of VHSV in olive flounder ( Paralichthys olivaceus ) was determined to be 10 3.7 TCID 50 /100 μL. W...

A new species of the whalefish genus Cetomimus is described based on eight female specimens from the Japanese seas, eastern Australia and the South Atlantic. The females of the new species, Cetomimus papilio sp. nov ., can be distinguished from its congeners by the presence of tent‐like lateral‐line flaps that are wider than the lateral‐line canal, lateral‐line pores 11–14, internal cavernous tissue surrounding the anus and th...

Background: Underwater adhesion of polymeric adhesives is highly desirable in specific applications such as wound dressings, wearable devices, bioelectronic devices, biosensors, and water pipeline leakage repairing. However, underwater bonding is considerably different from bonding in air because interfacial water molecules substantially weaken the intimate contact adhesion between the adhesive and submerged surfaces, thus sig...

Viral hemorrhagic septicemia virus (VHSV) is a major pathogen in olive flounder ( Paralichthys olivaceus ) aquaculture, leading to high mortality rates and significant economic losses. Recurrent outbreaks underscore the need for a deeper understanding of the early‐stage adhesion and infection mechanisms of VHSV. To address this gap, this study investigated the adsorption and replication dynamics of VHSV in various olive flound...

A new species of the roughy fish genus Hoplostethus , subgenus Leiogaster , is described based on three specimens collected from Sumatra, Indonesia. This species can be distinguished from its congeners by the following characteristics: gular region covered with ctenoid scales; pelvic‐fin spine smooth on its anterior edge; head depth subequal or smaller than its length (37.2%–38.6% standard length [SL], or 94.7%–99.2% head leng...

A new species of the roughy fish genus Hoplostethus is described from 11 types and a non‐type specimen collected from Taiwanese waters. It can be distinguished from its congeners by a combination of characters: pectoral‐fin rays 14–17 (modally 15–16); pyloric caeca 65–84; total gill rakers 19–20; predorsal scales 18–22; oral cavity, branchial chamber, top and underside of tongue, and peritoneum uniformly black; distal margin o...
