Size
"which vary in size from very small to medium sized" doesn't mean anything clear or objective... This kind of phrase should be avoided in an objective factual Wikipedia article. A tusk shell expert should indicate the average sizes of those life forms, as he/she should indicate the smallest observed in nature and the biggest observed in nature... Any volonteer ?

 * Good luck waiting for a "tusk shell expert": there are probably only about 20 scaphopod experts in the world. However, I will attempt to give a size range based on Abbott's "Compendium of Seashells". Invertzoo (talk) 13:51, 18 July 2010 (UTC)


 * It turns out I know one of those 20 people (actually the number is probably closer to eight, I think). It looks like this particular point has been addressed by now, but let me know if you (or anyone else) have other questions about these creatures not answered by the article and I will be glad to pass them on to him.  It's a very small field, Invertzoo is absolutely correct about that.  KDS 4444  Talk  01:02, 13 June 2015 (UTC)

Species of scaphopod used by Northwest Natives
Just wanted to point out that the species listed under "Human Use", Dentalium hexagonum, is an Indo-Pacific species and certainly not used by Northwest Natives! The section correctly mentions Dentalium pretiosum, which was the species used (although the genus should be Antalis). Also, Dentalium hexagonum is Paradentalium hexagonum. — Preceding unsigned comment added by 209.112.136.83 (talk) 02:55, 25 July 2016 (UTC)

Updates to Development, Evolution, and Anatomy
Hi, I've added an evolution section to encompass the fossil record section as well as a new phylogeny section given the interesting controversy over scaphopod phylogeny. I also added a bit more info to the anatomy section based on a couple new studies. I will also be updating the development section with some new studies on scaphopod early development.
