ok... it appears that female octopi die after tending their
eggs.... is this correct?

the story:

Aging Octopus Finds Love at Last


By MARY PEMBERTON, Associated Press Writer

ANCHORAGE, Alaska - It looks like J-1 is in love. After meeting the very fetching and slightly younger Aurora, he changed color and his eight arms became intertwined with hers. Then, the two retreated to a secluded corner to get to know each other better.

We're talking about giant Pacific octopuses here.

Aquarists at the Alaska SeaLife Center in Seward introduced the two Tuesday, and evidently they hit it off: Spermatophores were seen hanging from J-1's siphon.

"We really were not sure he had it in him," SeaLife Center aquarium curator Richard Hocking said Wednesday.

Love almost passed J-1 by. At 5 years of age and 52 pounds, he's reaching the end of the line for his species, the largest octopus in the world. J-1 is in a period of decline that occurs before an octopus dies. His skin is eroding. His suckers have divots.

"He's not as strong as he used to be," said aquarist Deanna Trobaugh.

With so little time left, J-1, who was collected on a beach near Seldovia in 1999 when he was about the size of a quarter, wasn't going to let the sweet Aurora slip through his eight arms.

Aurora sank to the bottom when aquarium staff put her into J-1's 3,600-gallon exhibit tank and promptly made the first move, reaching out to touch J-1 before retreating to her corner. But J-1 was soon in hot pursuit.

"They both were gripping the back wall of the tank. He just about covered her completely," Hocking said.

The two remained intertwined for about eight hours. It's possible that during that time he passed his sperm packet to her, Hocking said. When they separated, J-1 flashed some colors, turning almost white and then dark red.

"It looks like instinct took over during that encounter and they did what they were supposed to do," Hocking said.

If Aurora did accept J-1's spermatophores, she will produce 60,000 to 100,000 eggs. If with many, many children, Aurora — who was about the size of a grapefruit when she was found in 2002 living inside an old tire in front of the SeaLife Center — will stop eating while she tends her eggs. She will then weaken and die — a fate that J-1 also seems soon to meet.

"The goal for this was to let him lead a full life," Hocking said.

Yep. Soon after the eggs hatch. That is an cool article, Andy.

that's sad... dang...
 
Awwww. That just warms me right down to my suckers.
 
There have been experiments done where "some gland" regulating body rhythms or hormone production was removed in octopods, and this extended the animal's life for a few months beyond the natural limit. This is the only known method for prolonging their lives.
Most cephalopods have some internal clock that most decidely shuts down the critter following either spawning or egg hatching. It's a little weird... possibly an evolutionary flaw.
 
hmmm... so the female really only gets to mate and lay eggs once, right?

how about the male? do they survive mating to mate again?
 
Octo's typicaly stop eating all together after laying eggs. They also do not live long at all. The typical Octo usually only lives 2 years max. I've had several of them in aquariums, and they are extreemly intelligent. The pet industry tries to avoid shipping them at certain times of the year because of the egg factor. The very first one I got, laid eggs withing a month and died about a month later. It was very sad to watch her waste away.
 
Most animal behaviorists agree that if octopods lived longer, they'd be pretty freaking intelligent, ranking up with monkeys or even chimps. That 2 year figure badassbill gave is pretty solid for most octo's, alas.

How smart are YOU if you only lived to be two years old?
