Scaled reference drawings of architeuthis?

Hi everybody,

I'm into 3D computer modeling, and am trying to find some good clear reference images to use in modeling a variety of squids, particularly architeuthis. Good line drawings showing the essential details would probably be easier for me to work from than photographs. A set of images showing the top, side, and front view at the same scale would be excellent. Also, something showing the arrangement of arms and tentacles would help. I’ve searched the web and not spotted this, though I could easily have missed it.

Thanks in advance for your time and input, :smile:

Here’s a first cut at a front view of architeuthis showing the arrangement of the arms and tentacles.



The image is probably way out of proportion, and I doubt the cross-section is circular as shown here. Any criticism, tips, comments, or pointers to help make this more accurate would be more than welcome.:smile:

Carl,

That's absolutely brilliant! That's exactly how I imagined the arrangement to be, though hopefully Steve and/or Kat should be able to verify it.

For your interest, here's a diagram that (hopefully) will be of interest that I adapted from a image on the TOL pages for an old post which compares the arm arrangement in the various groups of coleoid cephalopods. If interested the original discussion was here, buried deep in the archives: Why Eight Arms?

I'm looking forward to seeing your finished images!

Phil

Hi Phil, thanks very much for the comments, and thanks too for the link and image. :smile:
On the Decapodiformes, do you know if the angles between the arms are accurate?

It’ll be a while, but I’ll post some images if I can get anything decent built and rendered.

Hi Carl. Scale drawings .... hmmmm. Problem is that individuals between ~ 6cm mantle length and 90cm mantle length (male) are unknown.

Your image looks like it's based on the Monterey Bay Archi model, in which the tentacles come from within the arm crown, from separate pouches, between the 3rd and 4th arms on either side. They should be between the 3rd and 4th arms, but outside the arms. I probably do have some pics in the office that will help explain this, and will post them online when I'm back in.

There's also a very well-developed 'web-like' membrane that surrounds the beaks (buccal membrane) that everyone overlooks. Go get yourself a squid from the local 'squid shop'/supermarket and have a look at this structure; trying to explain it will only confuse you to bits. I also have pics of this, and will post them (as soon as I can find them).

Are you modelling a male or female .... or both?

Hi Steve, thanks for replying here :smile:

Life size is fine then, it’ll give me a chance to exercise the “fit to screen” option on my browser. :wink:

I’m looking forward to seeing any pictures you might have illustrating the tentacle placement and the buccal membrane. I’ll also rummage through some local bait shops and super markets and see if I can get a first hand look.

As far as the gender of the model is concerned, I really hadn’t thought it out that far yet, though at some point I’ll have to decide. If the main gender difference is size, then the same model with minor modifications will work for either gender.

Going by what you said about the tentacles being outside the arm crown, and trying to jibe with the image of the Atlantic architeuthis toward the bottom of the Tree of Life page, I modified my front view layout as follows:



This is probably closer to reality than the first image, but are the tentacle bases out far enough?

Once again, thanks for your input here, I really do appreciate it 8)

Carl,

Here's a great image I found on this site. I can't verify how accurate it is but (in my ignorance) it looks pretty good to me. For some reason it was posted upside down on the website so I've inverted it for you. Please click on the image below.

Ta, Phil
