Open AccessGene expression profiles of dicyemid life-cycle stages may explain how dispersing larvae locate new hosts
Metazoans have evolved a great variety of life histories in response to environmental conditions. A unique example is encountered in dicyemid mesozoans. In addition to a highly simplified adult body comprising...

Chapter
Dicyemids
Dicyemids are the most common and characteristic endosymbionts found in the renal sac of benthic cephalopods. In this chapter, we introduce biology and diversity of dicyemids of European typical cephalopods, Octo...

Protist (Ciliates) and Related Diseases
Ciliates are one of the most common protistan parasites in cephalopods. In this chapter, we have undertaken to describe the biology and diversity of parasitic ciliates in European cephalopods and give diagnosi...

Open AccessThe phylogenetic position of dicyemid mesozoans offers insights into spiralian evolution
Obtaining phylogenomic data for enigmatic taxa is essential to achieve a better understanding of animal evolution. Dicyemids have long fascinated biologists because of their highly simplified body organization...

Diversity and Morphological Adaptation of Dicyemids in Japan
Dicyemid mesozoans (phylum Dicyemida) are the most common and characteristic endosymbionts found in the renal sac of benthic cephalopod mollusks, a unique environment in which they spend most of their life. Di...

Redescription of Dicyemennea eledones (Wagener, 1857) (Phylum Dicyemida) from Eledone cirrhosa (Lamarck, 1798) (Mollusca: Cephalopoda: Octopoda)
Dicyemids are common parasites found in the kidneys of many cephalopods. Species identification previously relied on old species descriptions containing considerable confusions, casting doubt on taxonomy and i...

Two new species of dicyemid mesozoans (Dicyemida: Dicyemidae) from Octopus maya Voss & Solis-Ramirez (Octopodidae) off Yucatan, Mexico
Two new dicyemid species are described from the endemic cephalopod Octopus maya Voss & Solis-Ramirez collected off Yucatan, Mexico. The renal sacs of 40 juvenile and adult octopuses from four localities were exam...

Open AccessDicyema Pax6 and Zic: tool-kit genes in a highly simplified bilaterian
Dicyemid mesozoans (Phylum Dicyemida) are simple (8–40-cell) cephalopod endoparasites. They have neither body cavities nor differentiated organs, such as nervous and gastrointestinal systems. Whether dicyemids...

A new species of Dicyemennea Whitman, 1883 (Phylum Dicyemida) from Sepia latimanus (Mollusca: Cephalopoda: Decapodidae) off Okinawa, Japan
A new species of dicyemid mesozoan is described from a cuttlefish Sepia latimanus Quoy and Gaimard collected off Nago, Naha and Onnason, Okinawa Islands, Ryukyu Islands, Japan. Dicyemennea ryukyuense n. sp. is a ...
