... response. Vision Electroretinogram Polychaete Spectral sensitivity Visual ecology Sabellidae Radiolar eyes, found on the feeding tentacles of sabellid and serpulid tube worms, are unusual visual sensors ( Bok et al., 2016 , 2017b ). The radiolar tentacles project from the worm's head...

... whether the tetrapeptide nereithione (cysteine-glutathione disulfide), known to be released by females of the polychaete Nereis succinea to trigger spawning in male N. succinea , can also be used at lower concentrations to guide males to the females. Low concentrations of pheromone elicited increased swim...

...Florence Pradillon; Nadine Le Bris; Bruce Shillito; Craig M. Young; Françoise Gaill SUMMARY Dispersal and colonisation processes at deep-sea vents are still not fully understood, essentially because early life stages of vent species remain unknown. The polychaete worm Alvinella pompejana forms...

... that is pronounced at high oxygen saturations. When fully saturated, the hemoglobin binds sufficient oxygen for only 31 min of aerobic metabolism. However, these polychaetes can withstand extended periods of anoxia both in the absence and presence of 1 mmoll -1 sulfide( TL 50 =approx. 5.5 and 4 days, respectively...

...U. Hoeger; J. F. Dunn; C. Märker ABSTRACT The concentrations of adenine nucleotides (AMP, ADP, ATP) were determined in coelomic cells (eleocytes) of the polychaete Nereis virens . In cells of immature and male animals, total ADP and AMP contents (each 10–15 μ mol ml −1 packed cell volume) greatly...
