Scientists expressed on Wednesday they were surprised to confirm a chimpanzee and an orangutan swimming and diving in water, a skill that primates were thought to have lost long ago. Developmental researchers Renato and Nicole Bender made the overpowering wonder observation while filming two primates raised in captivity in the United States.

Furthermore, Renato Bender from the South African University of the Witwatersrand's School of Anatomical Sciences, said in a statement that they were extremely surprised when the chimp, Cooper, dived again and again into a swimming pool in Missouri and appeared to feel very comfortable. It was undoubtedly unexpected behaviour for an animal that is considered to be very fearful of water.
