Dear Colleagues, in a series of recent reports we have confirmed the earlier results from a beluga whale (Delphinapterus leucas) population in the White Sea, that calves prefer to swim to the right of their mothers, thus keeping them in the left eye hemifield of vision. The same is true for wild Orcas. More detailed account for the influence of escort condition, calf age, research boat approach or population differences you may read in:
