It was long thought that Anomalocaris was an apex predator of its time and fed upon trilobites and other hard-bodied animals ( Read here about what trilobites fed on ). However, Anomalocaris have the characters one would expect to see of a predator in that time: large eyes, body size, mobility, and appendages posed to bring food to its maw. Some suggest that Anomalocaris fed on freshly moulted arthropods when the shell was relatively weak. Indeed, some may not have fed on hard-bodied trilobites and preferred soft worms or even fed primarily as cannibals. However, they remain an important part of the Cambrian ecosystem and the story of how life evolved from the “Abnormal Shrimp” to us.
