Distribution This species from the hallasi group was described from deep, subtidal localities off the coast of
Greenland, but was later reported from the shallow subtidal zone in the Mediterranean basin (also in marine
caves), and warm water in the tropical zone of the Indian Ocean. Recently, it has been reported from the deep
subtidal zone of Faroe Bank and the shallow subtidal zone in the Black Sea. In our opinion, similar to S.
nanoqsunguak, specimens of S. qivitoq from the Mediterranean basin and tropical waters need re-examination
to be sure they belong to this species (see remarks for S. nanoqsunguak). Kristensen & Higgins (1984a)
described this species as parasitic on bryozoans. It is similar to another parasite: Styraconyxinae, Tetrakentron
synaptae, which feeds on its host, the holothurian Leptosynapta galliennei. [details]
