Seattle aquarium cancels octopus sex show because of cannibalism fears?

A friend of mine just sent this one, and I must admit I had no clue. Apparently, the Seattle WA aquarium has a bit of a sense of humor, and it's been a tradition there to have an octopus sex show on Valentines Day. Well, a male and female octopus are put in the same tank and allowed to do whatever comes naturally. But this year, the show was cancelled, as the aquarium staff feared that the 80 lb male would eat the 40 lb female after copulation. Pity. I also learned that in octopi, females are generally larger than males, and the larger females often eat the male after copulation. I had known this is the case in black widows and praying mantises (especially in captivity--I reckon they're a tad stressed), but I hadn't realized this was the case in octopi. Would you go see an octopus sex show? Did you know that the females often eat the males after copulation? This whole thing kind of reminds me of a certain ex-girlfriend, but I won't go there right now.
