A report in New Scientist describes how northern bottlenose whales may look after each other when they are sick. The whales are more likely to stick together when individuals are poorly or emaciated, according to the report.
This behaviour could be a form of social support, though the exact reasons are not yet clear. The observation adds to evidence that caregiving may be part of the social lives of some whale species.
