Inverterbrate with the longest life?

[harwin]

Just curious to which of the (bugs) inverterbrates has the longest life? I know that some Brachypelma Tarantula can live up to 30 years...

thanks,

Hadrurus Arizonensis can live for 20 years, maybe 25.

it will be tricky to find the single most long lived bug out of all invertebbrates since alot of things we havnt kept from birth to death.

If I was betting, it would be on an arachnid of some kind,however I don't have a clue how long a lobster or some other crustaceans live. :?

I believe I remember a nature program about Atlantic lobsters saying they may live for ~80 years, but don't quote me on that!

i have a blue lobster and i had it for 5 years and it just molted 2 weeks ago (first time in 8 months). and i had one that was pregnet for 4-5 months, so they live for a long time aswell.

From search on google seems like for lobsters the popular figure mentioned is 15years... Some even estimate it to be at 50 - 150year... wonder who is keeping track... lol..

Anyway found out that hermit crabs can live up to 30 years..

amoebas reproduce through splitting and supposedly don't actually age which means some may be millions of years old.

Yeah, but how would you keep track of that? I mean, if you have one amoeba and it splits, then you wouldn't know which one is the "original" amoeba. So it's like, you'd then have two amoebas whose age you'd have to keep track of. Then they'd both split, and you wouldn't know which of the 4 amoebas to call the original amoeba. So then you'd have 4 amoebas whose age you have to keep track of. Then you'd eventually have a huge colony of amoebas (I don't know if "colony" is the right word, though). And some of them would always be dying off. But how do you tell which ones are dying off? Does it even matter? If you have an ongoing colony of amoebas, does that mean that the original amoeba has become immortal? Or does the simple act of splitting mean that the parent has died during the creation of its offspring? Like, if one amoeba turns into two amoebas, and you can't tell which amoeba to classify as the original amoeba, wouldn't it be more convenient to think of the original amoeba as having ceased to exist? And if they're BOTH the original amoeba, then doesn't that, by extension, imply that amoebas are immortal?

Hi,
Read this: http://www.eurekalert.org/pub_releases/2003-11/osu-rsu110403.php
It claims that some sea urchins may live for up to 200 years.

I would argue the second option, just because it's more interesting to think about

In Robert Heinlein's (is that how you spell his name?) Sci-Fi classic "The Puppet Masters" Earth is invaded by a race of parasitic amoeba-like organisms who attatch to the backs of humans and control them. Because these creatures reproduced by splitting, each individual had memories dating back to the orgin of the species!

Oh , yeah...the queens of som termite species are known to live 30-40 years.

I read somewhere that anenome have no definite lifespan.

I hear horse-shoe crabs can live for quite a while.

 

[Elytra and Antenna]

I have a horshoe crab (3.5 inch carapace) that has not molted yet and I got it on January 4th 2003. When I had smaller ones they would molt every one to three months.

corals and anemones have an undeterminable lifespan. unless there is some environmental interference, they can basically live forever unless i'm mistaken.
