"If you stand on one of Australia’s southern shorelines at this time of the
year, you might be lucky enough to spot a southern right whale (
Eubalaena
australis) swimming in the shallow waters.
These ocean giants have migrated from the Southern Ocean and Antarctica to
breed, give birth and to rest. If you’re really lucky, you may even see one of
them resting upside-down.
At first glance, this perplexing behaviour, which has not been reported in
other large whales, may make you think the animal is sick or injured. But our
new paper, published in the journal
Mammalian Biology, suggests quite the
opposite.
It may actually be an indicator of a healthy mother carefully managing her
energy reserves during one of the most energetically demanding periods of her
life."
