A little beluga whale has just been born in the relative warmth of a river estuary. His mother, an old and experienced female, is only joined by a young nursemaid who will help keep watch over the newborn calf for a while. Most mothers don’t sleep for several weeks after the birth of their calf. Too busy they are with ensuring its safety, keeping it away from predators and making sure it doesn’t wander off. Although perhaps the nursemaid’s watchful eye will allow this mother to sleep for a few short moment nonetheless.
