Anomalocaris

Summary
Anomalocaris was one of the first underwater Super-Predators during the cambrian period. It mainly fed on small trilobites living on the sea floor.

Appearance
Anomalocaris grew up to 2 metres long and sported a pair of 'arms' with tough spikes in front of its mouth, which it probably used to grapple it's prey. It had two bauble-like compound eyes on the top of its head, for it was one of the first animals to use eyes. It was an arthropod with ridgid plates over it's body.
