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
