Article Correctness Is Author's Responsibility: Family crucial to orca survival

(CNRS) Orcas live in stable, structured social groups. And their survival directly depends on it. Scientists were able to show that surviving orcas from a decimated family adopted 'erratic' social behavior, moving from group to group. The weaker these social ties, the greater the animals' likelihood of dying. As these orcas are probably not completely accepted by the new groups they join, they are likely to be given less access to food than the regular members of the social unit and eventually die.
