Cyclocosmia Spider
This is the Cyclocosmia spider, and it's incredible abdomen looks like an ancient coin! This genus spider lives in burrows and it uses the hardened disc at the end of its abdomen to clog the entrance when it's threatened.
A bee is a miracle of Nature! Its large body proportions and a small span of short wings discourage logic and all the laws of physics! It flies, but it does not know that, logically, it cannot fly!!!
