Some random facts i found on the internet

6. Octopuses and squid have three hearts

You surely know what it feels like when your heart starts pumping wildly, so imagine what it must be like for an octopus or squid, which each has. 

The cephalopods both have one systemic heart that circulates blood around the body and two branchial hearts that pump blood through the gills.

Have you watched finding dory? If you already have, i'm sure you would know this.
