Problem solving and tool use in three species of otter
Sea otters are well known tool users, yet the cognitive capacities of other otter species have been sparsely studied. Precedent exists for non-tool using species closely related to native tool users to display comparable abilities under experimental conditions. The social intelligence hypothesis …
