... was always used on the day that it was collected, as prolonged storage can affect slime viability ( Böni et al., 2017 ). Both species of hagfish were collected using baited traps at a depth of ∼100 m. Atlantic hagfish ( Myxine glutinosa Linnaeus 1758) were collected 10 km southeast of Appledore...

..., we analyzed videos of Atlantic hagfish ( Myxine glutinosa ) and Pacific hagfish ( Eptatretus stoutii ) moving through narrow apertures in the lab. We measured changes in body width as the animals moved through these openings and documented the behaviors associated with this ability. We found...

...J. E. Herr; T. M. Winegard; M. J. O'Donnell; P. H. Yancey; D. S. Fudge SUMMARY When agitated, Atlantic hagfish ( Myxine glutinosa ) produce large quantities of slime that consists of hydrated bundles of protein filaments and membrane-bound mucin vesicles from numerous slime glands. When the slime...

...Andrew J. Clark; Adam P. Summers SUMMARY As in gnathostomes, the hagfish feeding apparatus includes skeletal, dental and muscular components. In the present study, we examined feeding morphology and kinematics in two hagfish species, Eptatretus stoutii and Myxine glutinosa , representing the two...

...Gabriele Müller; Angela Fago; Roy E. Weber SUMMARY Hagfish hemoglobin (Hb) is considered to represent a transition stage between invertebrate and vertebrate hemoglobins. The Hb system of Myxine glutinosa consists of three monomeric hemoglobins, which upon deoxygenation associate to form primarily...

...Thomas Peters; Robert E. Forster; Gerolf Gros ABSTRACT The bicarbonate permeability of the plasma membrane of intact hagfish ( Myxine glutinosa ) red blood cells and the intracellular carbonic anhydrase activity of these cells were determined by applying the 18 O exchange reaction using a special...

...Nicholas J. Bernier; Steve F. Perry ABSTRACT An in situ saline-perfused systemic heart/posterior cardinal vein preparation of the Atlantic hagfish ( Myxine glutinosa ) was used to assess (1) the ability of the chromaffin tissue to release catecholamines in response to adrenocorticotropic hormone...

...Marianne Johnsson; Michael Axelsson ABSTRACT The effects of preload and afterload on the performance of the systemic heart of the hagfish Myxine glutinosa were investigated before and during sotalol treatment using an in situ perfusion technique. Elevation of input pressure (preload) increased flow...

...Tes Toop; John A. Donald; David H. Evans ABSTRACT The character of natriuretic peptide receptors (NPRs) in the kidney and aortae of the Atlantic hagfish Myxine glutinosa was determined and compared with that of NPRs in hagfish gills. The relationship of hagfish kidney and aortic NPRs with NPRs from...

...Tes Toop; John A. Donald; David H. Evans ABSTRACT Specific binding of iodinated natriuretic peptides 125 I-ANP and 125 I-CNP was examined in the gill of the Atlantic hagfish Myxine glutinosa by tissue section autoradiography, saturation and competition analysis of binding to membrane preparations...

...Steve F. Perry; R. Fritsche; S. Thomas ABSTRACT A variety of in vivo and in situ experiments were performed on the Atlantic hagfish ( Myxine glutinosa ) (i) to characterize the levels of circulating catecholamines during acute stresses, including hypoxia, anoxia or physical disturbance (air...
