0:00Squids have an extremely complex,

0:03interesting sex life. Here you see a

0:05male and a female. The male on the left

0:07has been fighting off other males to

0:08repair the female. And now he's showing

0:10a dual pattern. He shows courtship and

0:12love on her side, fighting on the other.

0:14Watch him when she shifts places and you

0:17see that he has fluidly changed the love

0:19courtship pattern to the side of the

0:21female. So, this kind of dual signaling

0:23simultaneously with a changing

0:25behavioral context is really

0:26extraordinary. Takes a lot of brain

0:28power.
