Otters 'juggle' stones when hungry, research shows

Published May 22, 2020

Rumble Otters are often observed lying on their backs playing with rocks; rolling them around and batting them into the air. The reason for this so-called 'rock juggling' hasn't been fully understood, but a new study from the University of Exeter suggests that hunger is likely to be the main driver for this behavior.

    a sea otter enhydra lutris will use the same rock its entire life to break open shellfish. These land otters lutris canadensis may have a similar trait but no need for using the rocks as tools but have the ability to if needed. Seems unique because in nature theres no room for such wasted.energy
