FUN FACT:


There are over 300 species of octopus with the lightest weighing less than a gram and the heaviest weighing 600 pounds! All octopi have eight arms, but originated from the ancient cephalopods which had ten arms and a shell. Over time, these cephalopods evolved into mollusks, which lost two arms and the shell for better mobility and speed, making them better hunters and better at evading capture.


While humans have one heart, octopi have three; two to pump blood to their gills and one to pump blood to the rest of their body! They also have arms that can think completely independently and if severed, can grow back on its own!
