I have, thanks. That now appears to be a couple of links. Could you summarise in your own words how auto-cannibalism is a key to understanding the longevity of the surface vertebrate eye? :coffee:

Sure (actually I did years ago on this site, but it's lost in the years and thousands of posts and lack of a search engine!

There is a site search and other search engines work too, I read. I look forward to you posting the relevant forum link...
As I have already said in this somewhat disjointed conversation, the cannibalism is only half the process of opsin disc replacement - new discs (with new opsin molecules) are constantly being made at the front end of the cell.

One would have expected such a process to be included on the key diagram. Heigh ho.
