Redescription of a brooding nemertine
, Cyan-ophthaima obscura (Schultze) gen.
Nocturnal surface activity of endobenthic nemertines
on tidal flats.
Further taxa (nemertines
, bivalves, amphipods, ophiurids, holothurids, pycnogonids, acari) were restricted to the mangrove fringe (site HI) and the adjacent mudflat.

Locomotion in British terrestrial nemertines
and planarians: with a discussion on the identity of Rhynchodemus bilin-eatus (Mecznikow) in Britain.
The relationships among the lophotrochozoan taxa are still somewhat poorly resolved (Dunn et al., 2008; Paps et al., 2009), but the core group (lophotrochozoan sensu stricto of Paps et al., 2009) includes molluscs, annelids, nemertines
, the lophophorates, platyhelminths, and other smaller phyla).
Although detailed analyses are lacking, the few data available indicate that the random-type of muscle formation may also occur in nemertines
(Maslakova el al., 2004).
Other invertebrate larvae from taxa such as polychnetes, nemertines
, echinoderms, and phoronids have embryonic nervous systems that are very similar to those of molluscs (Hay-Schmidt, 1990a, b, c; 1995).
