Hi

I want to know your opinions about the title. :biggrin2:
There´s a limit based on physics, on lifespan, on predation vulnerability, on food availability, etc...? Surely, but how and why?
Thanks.

Steve have made some guesses in the past so maybe he will chime in. If I remember correctly :old:, I think his estimate was about 1 ton (2,000 pounds)

Unless there are bigger species out there we haven't yet discovered, I would place a bet at a 600 kg maximum, ML at 2.80, maybe 3.00 meters, Steve, you still at 750? I am free to express my doubts at the 495 kg assessment of the Te Papa specimen; would put that in the 375 kg range, personally. This is based on the slightly smaller specimen we were able to weigh in parallel. I would love for them to grow a lot bigger, but this would be my current best guess. Then, there's the Lusca :wink:

Hum...
The beaks found in sperm whales didn´t suggested about bigger sizes?
Which one was the biggest giant squid ever found?
Isn´t possible to exist bigger ones?
Were the biggest giant or colossal squids found all mature and at maximum size range ( not talking about possible record size naturally)?
This site talks about an estimation of 100 feet for one that it´s pieces were found on sperm whale stomach : http://www.unmuseum.org/squid.htm
Is this false or true? Apart from some stories mentioned there, I want to take all the possible facts from it.

The larger Te Papa specimen weighed 495 kg (frozen). Once over 750 kg they can get as big as they want - nobody will be arguing with them!

good question, i'm not aware on last informations on possible weight.

The only one thing I know is existence of beaks from sperm whale's stomachs, suggesting bigger specimen of M HAMILTONI than the "Te Papa" sample

Concerning Architeuthis (or others species) suckers scars on sperm whales skin could suggest quite bigger size thant known specimen ..

the rare testimonies ( recents or not) are not reliable to my opinion except some specific cases including the one in my signature.

Chris, wouldn't it be more appropriate to say that the container containing the frozen squid plus attached frozen water weighed 495 kg? There was quite a bit of ice in there. We could split the difference? 435 kg?

PS: a 45 ton bull sperm whale might disagree with the latter part of your statement :wink:
