A large pod of spinner dolphins swim in the clear blue water off of Oahu, Hawaii. These animals hunt in the deep offshore waters at night, before returning to shallower coastal regions in the morning to socialize and rest.
Spinner dolphins are among the most social of all dolphin species and are rarely seen alone or even in small groups.
After humans, dolphins have the largest brains in the animal kingdom, relative to body size. Despite this fact, their world is very different than our own and the ways in which they use their brain is fascinating. Dolphins see much of their world acoustically, using echolocation (i.e. sonar) to determine the location of objects and distances. Dolphins also sleep with one half of their brains awake, as they need to be constantly alert for predators and because they are voluntary breathers.
