Ophyotrocha is easy to keep in the laboratory and has therefore been used in several studies of evolution and speciation. The phylogenetic relationships within the group are, however, still not clear and morphological and molecular data are contradic

For more than a century, it has been pointed out that most features of the original description of Ophryotrocha puerilis Claparede & Mecznikow, 1869, probably based on a mixed population of two sympatric species, agree better with the subsequently de

Crossing experiments were conducted between the Naples I (NI) strain of Ophryotrocha labronica labronica, three strains of O. l. pacifica from Japan (M3), Hawaii (WH) and Los Angeles (LA), two strains of O. labronica from Australia and one from an un

Annelids of the genus Ophryotrocha are small opportunistic worms commonly found in polluted and nutrient- rich habitats such as harbors. Within this small group of about 40 described taxa a large variety of reproductive strategies are found, ranging

An undescribed dorvilleid belonging to the genus Ophryotrocha, Claparede & Mecznikow, has been collected in the harbor of Kyrenia, Cyprus, the harbor of Las Palmas, the Canary Islands, and has recently been reported from the Sand Island and Barber's

This paper reviews the group of gonochoristic Ophryotrocha species, known as the “O. labronica group”. This informal group is chararacterised by its unique maxillary P- and K-forceps and dorsomedian rosette glands. All members of the group are pr

Two new species, Dorvillea bermudensis sp.n. and D. albomaculata sp.n., with obligate asexual reproduction are described. Both are closely related to sexually reproducing members of the same genus. The new species undergo repeated fission of the arch

While sexual reproduction is conserved and almost ubiquitous, asexual reproduction in forms of parthenogenesis or agametic cloning from somatic tissue is less conserved. The phylogeny shows that agametic cloning is widespread but scattered with many

Ophryotrocha socialis n. sp. is described from laboratory cultures. Its requirements are those of a boreal and opportunistic species which does not survive at salinities below 20-25‰. It is a simultaneous hermaphrodite combining traits which otherw
