No one really knows why otters juggle pebbles, but one thing is for sure: whether they are tossing pebbles from one paw to another or rolling them up and down their arms and across their chests, otters are without doubt expert pebble jugglers.
Scientists have been looking for an explanation for some time now and have come up with a number of theories, but nothing conclusive.
Could it be that the otters are just relaxing and having fun?
What do you think?
