Opabinia regalis lived 500 million years ago during the Cambrian Period. It had 5 eyes, a proboscis, and a backwards mouth. It was about 2-3 inches long, and it ate plankton by catching it's proboscis, the feeding it up to it's mouth! The opabinia was also the awesomest creature alive!
Opabinias are very awesome!!

Get the Opabinia mug.A prehistoric sea creature that existed during the Cambrian period. Mainly looking very unusual and alien-like from most modern sea creatures today.
