In April 2009, a female chimpanzee named Sango, living in a captive group at the Noichi Zoo, Japan, gave birth to dizygotic male-female twin chimpanzees (male: Daiya, female: Sakura). The extent to which adult group members cared for the twins was investigated using a focal animal sampling method targeting six adults (one male) when the twin chimpanzees were two years old. Data were collected for an average of 6.78 h (SD = 0.79) per focal participant. An unaffiliated female adult of Sango was engaged in parenting Sakura as much as Sango. Given that Sakura was in lesser proximity to Sango than Daiya, Sakura's departures from her mother and her ability to gesture requests might have enabled non-kin adults to provide her care.

We report a case of paragonimiasis in a captive mandrill (Mandrillus sphinx) in a zoo in Kochi Prefecture, Japan. At autopsy, five adult flukes were detected from cysts formed in the lungs of the animal. The flukes were identified as Paragonimus miyazakii on the basis of morphological features of the adults and eggs in the feces. The ribosomal DNA sequence also corroborated this identification. The mandrill was possibly infected through the ingestion of the Japanese freshwater crab (Geothelphusa dehaani) wandering into the place of breeding exhibition. This is the first confirmed case of natural infection with P. miyazakii in non-human primates in Japan.
