Does anyone knows whether or not cephalopods (coleoids and nautilids) can vomit, i.e. produce regurgitate?
Here is an old octo poop image post, recent by geological standardsI would like to see recent stuff
Dr. Cooke,we speculate they can here:
Sykes, A.V., Almansa, E., Ponte, G., Cooke, G. and Andrews, P., 2020. Can cephalopods vomit? Hypothesis based on a review of circumstantial evidence and preliminary experimental observations. Frontiers in Physiology, 11, p.765.
@GavanMCookeDr. Cooke,
As a very recent convert to cephalophilia, I think I can safely say that I am alone in my extensive circle of friends and acquaintances who find this subject fascinating. I wonder, however, (a bit off-topic) how one could go about collecting and analyzing cephalopod fecal matter, as I suspect it would be immediately diluted and dissipated in the aquatic environment. I’m thinking primarily of the degree of ingestion of plastics to be found in wild octopuses.

From my experience, octopuses DO vomit and it's quite obvious in the tank's water when they do...
