Pair of Siamang Gibbon Apes

Betty also watched Siamang gibbons swing through trees at up to 35 mph. These apes regularly break into songs comprised of complex patterns and rhythms. Each pair's song combines three types of unique vocal patterns, which strengthen lifelong bonds and serve as territorial alerts.

Although Hobbs' brain is the size of a walnut, his species is one of the smartest animals in America. Some experts say Keas are as smart as a 4-year-old child.

Micro-Mini and Teacup "Pixie" Piglets Sleeping

Unlike dogs, pigs recognize themselves in the mirror. At just 10 weeks old, pigs can identify the reflection of a bowl of food, and then navigate around an obstacle to reach the food.

Betty White with Primo the Dolphin

Dolphins are the smartest animals in the world, which is why the U.S. Navy recruits them to seek out underwater weapons using their built-in sonar.

Chaser the Border Collie Book

The average dog can learn up to 165 words, but Chaser knows over 1,000. With training from her owner, John W. Pilley, Jr., she recognizes every one of her thousands of toys and learned the name of a new toy through deductive reasoning. (Photo courtesy of Chaserthebordercollie.com.)

When Betty introduced a male doll named Robert, Chaser promptly selected it among other toys when her owner asked her to get "Robert."
