So far only one
species has been described (in 1983, see right), but there are thought to be
more. They are less than 3 mm long and cling to sedimentary particles; this
makes detection difficult. They have an eversible, spiny stylets as found in
the Kinorhynchans, but it is not known if it is
everted in the same manner. |
