Olive and Otto
At the end of the 1950s, two North American river otters moved into their new home in the Children’s Zoo and made quite a splash in the neighborhood! The pair seemed to be constantly in motion. In the pool, they swam right side-up, upside-down, and on their sides, twisting and turning with the greatest of ease.
Yet, they never seemed too busy to answer a friendly “hello” from a Zoo visitor. When they heard a human voice, the pair would stop whatever they were doing, stand on their hind legs, and wriggle their faces at the greeter. It became known as their trademark “otter salute.”
