Anomalocaris, means "abnormal shrimp" is an arthropod- like sea monster that lived in North America during Cambrian period. Anomalocaris got it's name because it was believed to be multiple animals; it's front appendages were believed to be the hinder halves of shrimp ("strange" because their "head" was always missing), it's mouth was believed a jellyfish, and it's body a sea cucumber or a sponge. This mistake was only realized in the 1980s, providing the modern reconstruction as the meter-long flippered monster. Anomalocaris' eyes, on the caliber of only a few modern insects, were compound with around 30 thousand lenses. He would swim above the ocean floor, find prey, and shred it in three rings of teeth.
