Great Ape Ultrasound Studies


For more than 15 years, Zoo staff and volunteer medical professionals have performed ultrasound studies on our great apes. As a result of extensive positive reinforcement training by our staff, our great apes voluntarily participate in these painless studies – without restraints, sedation or anesthesia.

Ultrasound studies include heart studies of bonobos, gorillas and orangutans and fetal development studies of bonobos. Our Zoo was the first in the world to do these types of studies with great apes.
