Dear colleagues, we are pleased to announce the publication of the following paper: Pace DS, Mussi B, Miragliuolo A, Vivaldi C & Ardizzone G (2016) First record of a hagfish anchored to a living bottlenose dolphin in the Mediterranean Sea. J Mammal DOI: http://dx.doi.org/10.1093/jmammal/gyw022 First published online: 24 March 2016 Abstract An unusual observation of a hagfish (*Myxine glutinosa*) anchored to a living bottlenose dolphin (*Tursiops truncatus*) was documented in an encounter with a group of about 80 dolphins during an ongoing long-term research program on cetaceans in the central Mediterranean Sea, Italy. The body of the hagfish was observed extruding from the blowhole of the bottlenose dolphin showing a stereotypical surfacing–breathing pattern. The observation lasted 2h; photo-identification, acoustic, and behavioral data were collected. Succorant behaviors (i.e., “standing by”) from conspecifics and overlapping vocalizations during social phases were recorded. The dolphin was encountered again after 1 month in the same area without the hagfish, apparently in healthy conditions.
