    So, last night I started a thinking, and I have a question

    On average, who has a larger eye, Giant Squid or Collasal Squid? Is it still Architeuthis?

    :archi: VS. :mesonych:

    LET THE BATTLE BEGIN!

    I think the Te Papa specimen had a larger eyeball than any Architeuthis, but I'm not certain. I also don't know if it had a bigger pupil (all the better to see you with, in the dark).

    The eyeball of the record te papa Mesonychoteuthis I measured was (approximately) 245 mm across, whatever wikipedia or the press releases say (275 mm is bogus). Its pupil/lens was 80 mm across. The eye on the 170 kg 1.8 meter ML Architeuthis we had along for the ride was considerably smaller, 163 mm, but literature puts its maximum size at 250 mm. I have some doubts towards the validity of that statement; I would guess that with a maximum ML of 2.25 m it doesn't get much beyond 200 mm, but that's just me... I am not the world expert on the topic.... Steve?

    Steve is brain dead when it comes to recollecting figures like this Olaf. Nevertheless, Mesonychoteuthis wins, without a doubt. There's no contest as far as I'm concerned.

    Colossal squid would be my guess because they have a larger body mass... again I could be wrong :) All I know is they are both really big...

    You are right; as previously stated, there is no contest :wink:

    Uh.... okally-dokally, but what's all this got to do with cephalopod eye size? :confused:

    EnergyRecru, methinks you've posted to the wrong thread.
