The Pacific spadenose shark (Scoliodon macrorhynchos) is a species of requiem shark, in the family Carcharhinidae. It was once regarded as conspecific to the spadenose shark (S. laticaudus).[1]

Virology

Pacific spadenose sharks are identified as hosts of the Flavivirus Wenzhou shark flavivirus.[2] While currently unknown if Wenzhou shark flavivirus causes disease in infected shark hosts, it is thought that the virus moves horizontally from the gazami crab Portunus trituberculatus to shark hosts[3] in a manner similar to other Flavivirus infections such as Dengue virus, which cycle horizontally between arthropod (mosquito) and vertebrate hosts.
