Heard an Octupus leaves its arm behind when mating?

Question

O.o

Answer 1

no but if they are attacked they can break off and grow a new one.

Answer 2

I hadn't heard that one.  The male octopus has a specialized arm that stores the sperm and transfers it to the female.  

The male octopus dies a few months after mating and the female dies shortly after the eggs hatch. (bummer eh?)

Answer 3

really??....wow must be some rough play...hehehehe....
