This seems to suggest that the acid filled sack we know as the stomach acts as a filter for things that enter the intestines. It has different acidity levels in different species. Maybe one or more creatures had somewhat acidic guts to begin with, and that acid gradually became localized to a particular area? Without speculating too much, I can still think of various ways an acidic stomach could evolve over time.

Verbatim from the mouth of Jesus (retranslated from a retranslation of a copy of a copy):
"Do not judge, or you too will be judged. For in the same way you judge others, you too will be judged, and with the measure you use, it will be measured to you. How can you see your brother's head up his ass when your own vision is darkened by your head being even further up your ass? How can you say to your brother, 'Get your head out of your ass,' when all the time your head is up your own ass? You hypocrite! First take your head out of your own ass, and then you will see clearly who has his head up his ass and who doesn't." Matthew 7:1-5 (also Luke 6: 41-42)
