"Living Fossils" in Our Reef Tanks
 

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.

chitons are as prehistoric as it gets:P

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.

Diatoms also.

i have lots!!



even looks prehistoric.



ps.....marko hates this picture :P

:lol: ahhh yes

It looks glass or plastic.

As for diatoms . . . I have had those!

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

Horseshoe crabs. Creepy things... 450Million years old or so? :surprise:

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).
