Do Zoo Otters Love People Watching?

A recent study published in the Journal of Zoological and Botanical Gardens suggests that captive Asian small-clawed otters may not experience stress when they encounter human visitors. Veterinary researchers from Adelaide University in Australia tracked the behavior of six captive otters over six months, observing them for hour-long sessions across a six-month period.

The otters, housed in a naturalistic habitat with pools and logs, were monitored during their interactions with visitors and without human presence. The study found no evidence of stress in the otters when people were present, and in fact, the otters exhibited increased activity and visibility. Lead researcher Paige Klingner noted that visitors may have a positive or enriching effect on the otters' welfare, although further research is needed to confirm this.

The researchers acknowledged the difficulty in determining causation between otter activity and the presence of people. While the otters made more vocalizations when humans were around, it is unclear whether these noises were expressions of excitement or stress.
