Interval timing in cleaner wrasses
Research report (imported) 2005 - Max Planck Institute for Ornithology
Studies of cognitive interval timing up to now focused mainly on the range from seconds to some minutes. However, individuals often face situations where they must adjust their behaviour to longer (but not circadian!) intervals. Still lacking for this time range are data and theoretical models, which could explain how animals solve such problems. A marine cleaner wrasse is now the first example, that a not warm-blooded vertebrate is able to time several different intervals simultaneously without external cues.
