orangutan on the O Line
Jessie Cohen, NZP photographer

An orangutan on the O Line traveling on a series of towers connected by cables.

The O Line connects the Great Ape House with Think Tank, where some orangutans work with researchers on building language skills.

Think Tank is a special place in the Zoo where animal cognition is explored through interactive exhibits.
