Has anyone ever done a Speculative Evolution book or work on Carcinisation?

I think Diaspora by Greg Egan had a chapter with a crab planet, or maybe it was a crab universe. Its been a long time since I read it but I remember a scene where someone kind of turns themselves into a crab so they can talk to alien crabs about math and physics.

Maybe it can actually gain some activity.
