In California, a three-month old sea otter pup has to learn what’s safe to eat in a world enmeshed with humans, while in Sri Lanka, a seven-month old macaque is forced by his mother to toughen up to stay on top.

The animal babies are fast growing into their abilities, but every day brings new challenges to their success.
