A show I'm watching on TV right now (about an isopodish looking thing called a "nautilus") has me thinking . . . Are there any critters commonly stocked in our tanks that are relatively unchanged from prehistoric times?
Edit: the Nautalus is apparently a cephalopod.

You're correct. They're 400 million years old: they apparently have Devonian origins (so says Google). :) Cool! I haven't seen any in my system.

I think cyano is something like 3 billion years old, makes sense as to why it's so tough to get rid of!

Cyano is as old as the earth itself :P I think it started its journey when the earth became a "live-able" planet (as far I can remember reading it somewhere).
