Purpose Of Adipose Fin In Corydoras Aeneus

[Byron]

I came across this study and thought some may find it interesting.  As it mentions at the start, the purpose of the adipose fin--which is present on Corydoras and many catfish, as well as most (but not all) characins, the salmon, and some others--has generally been thought vestigial and without purpose.  This is another "assumption" turned on its head, as this study shows a clear purpose for this fin to the fish (Corydoras aeneus in the study).  Here is a link to the full paper:

How fascinating! I've often wondered about the origins of the adipose fin, so it's great to have some research to read, thank you very much for posting the link
