This topic is a follow up of a previous post (https://thefishvet.com/2012/08/31/do-goldfish-have-a-stomach/).
Recently, I was at Murdoch University and bumped into my first year lecturer for Anatomy, Assoc. Prof. Ken Richardson. Of course all conversations with me lead to fish… Anyway, I asked him this question… Does the goldfish have a stomach? I went into great lengths trying to get him to agree with me that they DO have stomachs based on the definition of a ‘dilated region in the anterior GIT’. He didn’t buy it and says that true stomachs have specialisations and has the ability for digestion at low pH rather than in the intestine where the pH is higher. The examples I gave about the cow stomach was explained away with this reasoning and that the rumen, reticulum and omasum are actually specialisations of the oesophagus rather than the stomach.
OK, I give up trying to prove I’m right on this topic…. until I get another opportunity…
One day… I can say AHA! I thought so! But sadly, not today 😦
