Checked: verified by a taxonomic editorEtymology The specific epithet gula, the Latin word for 'gluttony', refers to the fact that most of the type material was found attached by the pharynx to the body surface of other polychaetes: "They were usually attached to the body wall rather than to cirri and evidently held in place by a strong sucking action of the pharynx for when pulled loose the point of attachment on the body wall showed as a very distinct papilla" (Treadwell, 1924: 11).  [details]

From editor or global species database
Checked: verified by a taxonomic editorAssociation Lattig & Martin (2009: 23) suggest that the species Haplosyllis gula could be an ectoparasitic polychaete, with the broad pharynx of the species being an adaptation to this mode of life. However, the fact that most of the type specimens were attached to other polychaetes seems to be circumstantial, as stated by Treadwell (1924: 11) in his description of the species: "[Specimens were] attached to the surface of fragments of Leodice longicirrata Webster; to a small Glycerid, and to another Syllid, thought most of the specimens were on the Leodice. They were usually attached to the body rather than to cirri [...]. Eisig (1906 page 180) and Potts (1911, page 410) have described the ferocity with which syllids attack other annelids and it is possible that the attachment took place in the close confinement of the collecting dishes rather than in the open ocean. [...] In the specimens here described there was no evidence of anything more than temporary attachment." Instead of being ectoparasitic of other polychaetes, it seems more probable that the specimens lived as symbionts of one or more of the sponges that covered the dredged bottom, becoming attached to the polychaetes during the manipulation of the sampled material.  [details]
