Swiss wildlife photographer Franco Banfi has captured an absolutely
stunning photo of a tired pod of sperm whales fast asleep while floating in the
deep blue sea off of Dominica. Because of the the minimal amount of time that
cachalots spend at rest, this is indeed a rather rare photo as well.
In 2008 a team of researchers suggest that, unlike other cetaceans,
sperm whales (Physeter macrocephalus), Vulnerable (IUCN)appear to enter short,
but periodic, bouts of sleep throughout the day — an observation that Kaplan
says could hint that sperm-whales are actually “the least sleep-dependent
mammals known.”
After the pod woke up, Banfi captured an equally stunning photo of the
whales socializing with one another.
