Capybaras relax in an outdoor bath at Nagasaki Bio Park in Saikai, Nagasaki Prefecture, in this recent photo. The rodent bath is a popular attraction at the park.
Capybaras, whose habitats include the tropical Amazon River basin, dislike the cold. They are known for their love of hot springs, and at the Nagasaki park they can be seen relaxing under streams of water or soaking in the bath. Capybaras emerging from the water continue to warm up next to a heater.
The bath display will be open from noon till 3 p.m. every day until Feb. 29, 2016. (Mainichi)
