A pair of dolphins glide through the tranquil tropical waters of Honduras. Dolphins have the largest brains in the animal kingdom relative to body size, after humans, but their brains function differently than humans. Dolphins keep one half of their brain awake while sleeping because they are voluntary breathers and must also remain vigilant for predators. They also see much of their world acoustically using echolocation. For researchers, dolphin lives remain largely a mystery and understanding the full extent of how these complex animals live may take a long time.
