Hippos have a membrane that protects their eyes, which allows them to see underwater, according to a news release from the San Diego Zoo. That means Devi can watch the guests as they are watching her, the release stated.

Zookeepers report that over the last several weeks, Devi has grown stronger and more curious, and has started venturing into deepest parts of the pool.

Devi's mother, Funani, was never far away from her calf, and could often be seen nudging Devi back toward the shore, the release stated.

The calf was born on March 23 and shares the exhibit with her mom and father, Otis.

The hippopotamus is listed as vulnerable by the International Union for Conservation of Nature, known as the IUCN, according to zoo officials.
