| Research Abstract |
(1) Description of new species
Ten new species of dicyemid were found in five species of cephalopods. Three dicyemid species of Rossia pacifica and enteroctopus dofleini were redscribed.
(2) Phylogenetical relationship of dicyemids
The relationship of dicyemids was studied using the amino acid sequences of the gap junction protein, Innexin. The dicyemid was more closely related to mollusks and annelids than platyhelmintes.
(3) Coevolution
The phylogenetic trees of dicyemid species and the host cephalopods revealed that dicyemids and cephalopods did not co-evolved. Some dicyemid species change the host species, some co-speciated with the host cephalopods.
