Giant Isopod

The Giant Isopod Bathynomus giganteus is the physical embodiment of awesome. They are closely related to sow bugs, and live >9000 feet under the sea. Some time ago, a pic of these critters devouring their natural prey, the Dorito, was posted in a blog OL and an internets phenomenon was born.

Everyone <3 Isopod

The Doritopod pic was spammed all over blogs and forums, garnishing both amazement and disbelief, although many people thought they were looking at the remnants of the world's tackiest lobster dinner. Lusers made Giant Isopod fanart, t-shirts, and wrote songs dedicated to them, because the internet really doesn't have anything better to do.

The Zerg are already among us.
You knew lolcats would ruin this one eventually.
