A pod of Dusky Dolphins swim through the chilly, algae-thick waters of Golfo Nuevo in Argentina. A strikingly-colored species, Dusky’s can be found in pods numbering in the hundreds.

These acrobatic creatures often leap high out of the water, and - while in the sea - use communication to corral schools of anchovies as a means of feeding.

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.
