"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.
