Cockroaches
They say that the only things that will survive a nuclear holocaust are cockroaches and Wall Street bankers.
Here’s a bit about cockroaches I gleaned on the Internet. Stuart Wilde
“The Earth is covered with cockroaches. About 4,000 species thrive in diverse climates all over the world. The few species we know as pests have proven particularly good at adapting to changing environments. Cockroaches can live for weeks without food. If they have to, they can survive on postage-stamp glue. They can recover after 30 minutes underwater. They can withstand several times the radiation it takes to kill a human being. Cockroaches have been around longer than humans and could someday outlive us. They’re a lot tougher than most species”. (P. Stansberry)
