So I just saw your newest video of the octopus, it was so cool!
I found it extremely interesting, because I am going to teach some elementary school students about the evolution of squids!
This is a picture from my practice-dissection of a Loligo singhalensis, and I thought that the organs were really well shown, and you can clearly see the gill hearts (the branchial hearts) and the ink sack!
I really wanted to show you what we found inside this squid too, it was really awesome how much it had ate, and in what state the fish were in (half digested). I even removed its beak, to look at it!
But I can unfortunately only submit one picture, so if you could be interested in that, I would be glad to submit that one too!
You should do a video about the evolutoin of squids, it is a 400 million year, extremely interesting story, from when the mollusca started to form, until we got the decapoda today!
