Animals with bony tongues

Are/were there animals whose tongues contain bone(s), except Osteoglossiformes? 212.180.235.46 (talk) 12:19, 8 November 2022 (UTC)

While it is not strictly within the tongue, many vertebrates have a hyoid bone or analogues, which among other functions, support the tongue. --Jayron32 14:20, 8 November 2022 (UTC)

Hall of mirrors

The front page of this morning's Daily Mail has on it a picture of the front page of this morning's Daily Mail, which of course includes a picture of the front page of this morning's Daily Mail, and so ad infinitum. Is there a name for this phenomenon? 79.76.42.157 (talk) 13:35, 8 November 2022 (UTC)

See Droste effect (and also mise en abyme and infinity mirror). ---Sluzzelin talk 13:42, 8 November 2022 (UTC)

Or more generally, Recursion. --Jayron32 16:00, 8 November 2022 (UTC)

Temporary place to see that front page. --174.89.144.126 (talk) 20:14, 8 November 2022 (UTC)

Many years ago I came across a a pdf named A Primer to Contemporary Self-Reference by Thomas Bolander. I saved it on my PC and still have it, but it seems to have disappeared from the interwebs. I can only suggest Uroboros as a starting point. May your journey be fruitful and not end up deep in your own fundament. MinorProphet (talk) 01:47, 10 November 2022 (UTC)

You might like the demonstration here of the Mandelbrot set, which illustrates a related phenomenon in maths. Our article has images that zoom forever, at a smaller scale. Mike Turnbull (talk) 10:59, 12 November 2022 (UTC)
