August 8 - Nybelinia surmenicola
Nybelinia surmenicola is another tapeworm parasite that infects the salmon shark, Lamna ditropis. The sharks get these parasites when they prey on either fish or squid that are serving as the intermediate hosts for this parasite. Salmon sharks are interesting creatures, themselves, in that they one of the few fishes that exhibit homeothermy, or the ability to regulate their own body temperature. These sharks live in the northern Pacific ocean. At least one case of a human infection of Nybelinia surmenicola has been reported. A Japanese woman complained of severe pain in her mouth after eating uncooked squid. Doctors removed four larval tapeworms from her tongue and pharynx.
