How smart are orcas?

Interviewed for the Orlando Sentinel, Neuroscientist Lori Marino tells of how she and a team of researchers explored the brain of a dead killer whale with an MRI and found an astounding potential for intelligence.

Killer whales, or orcas, have the second-biggest brains among all ocean mammals, weighing as much as 15 pounds. It’s not clear whether they are as well-endowed with memory cells as humans, but scientists have found they are amazingly well-wired for sensing and analyzing their watery, three-dimensional environment.

The article is well worth a read, especially as it references Lori Marino and Hal Whitehead, both friends of whales and WDC.
