Different kinds of aquatic (water-dwelling) animals use similar tricks of the survival trade. This section demonstrates this point with a look an aquatic bird and a water-loving mammal.
The Asian elephant has a finger-like tip on the end of its trunk; the African elephant has two. These trunk tips can pick up objects as small as a blade of elephant grass.
