Trivia: How Many Hearts Does an Octopus Have?

In honor of today's International Cephalopod Awareness Day, here's today's octopus trivia:

An octopus has three hearts. Two hearts to pump blood through each of its two gills, and a third one to pump blood through its body.


It might also interest your readers to know that the esophagus of a cephalopod passes through the center of the animal's brain on its way to the gut. Good thing they have those beaks to take small, bite-sized chunks out of their meals!

I've just finished reading the book, "The Zen of Fish" and learned that the octopus also has a separate brain in each tentacle coordinated by one centralized brain in his head.
