[Annelida] Swarming 'worm'

[dfiege]

Hi all,

that sounds interesting and it does indeed look like an enteropneust.

There is a reference to a swarming enteropneust, Glandiceps hacksi 
(Marion, 1885) at 
http://www.marinespecies.eu/species.php?species_group=zmns&id=118&menuentry=groepen 

taken from Brusca & Brusca (1990).

There is another hint to Indo-Pacific species of the genus Glandiceps 
that leave the bottom and swim actively at the surface by Dawydoff 
(1966: 448/9) in the Traité de Zoologie Tome XI. He refers to Ikeda but 
there is unfortunately no reference given. Could it be this one:

seems to be in Japanese, available online but not for free.

Cheers,

Dieter
