Anomalocaris was a swimming creature which possibly used flexible lobes on the sides of its body to propel itself through the water. Its large head had one pair of large, possibly compound, eyes, and a disk-like mouth that resembled a slice of pineapple. Two large 'arms' with barb-like spikes were positioned in front of the mouth; Anomalocaris probably used these to grab prey and bring it to its mouth. Compound eye of a dragonfly Compound eye of Antarctic krill as imaged by an electron microscope A compound eye is a visual organ found in certain arthropods such as insects and crustaceans. ... For other uses, see Eye (disambiguation). ... male human mouth The mouth, also known as the buccal cavity or the oral cavity, is the orifice through which an organism takes in food and water. ... Binomial name (L.) Merr. ...


For the time in which it lived Anomalocaris was a truly gigantic creature, reaching lengths from an already large 60 cm (2 ft) to a staggering 2 m (6 ft 8 in). [1]


Anomalocaris has been misidentified several times. Its name originates from a description of a detached 'arm', mistaken for a separate creature. The mouth was mistaken for a jellyfish and called Peytoia, and the body was classified as a sponge named Laggania. According to ICZN rules, the oldest name takes priority, which in this case would be Anomalocaris. The name Laggania was later used for another genus of anomalocarid. "Peytoia" has been modified into Parapeytoyia, a genus of Chinese anomalocarid. For other uses, see Jellyfish (disambiguation). ...

Anomalocaris (285 words)
Anomalocaris, meaning "odd shrimp" were large creatures indeed, probably the largest animals in the Burgess Shale or the Cambrian Era about 60 cm long.
Anomalocaris had a long, oval-shaped head, large eyes, feeding appendages at the front that look like combs, and a circular mouth underneath.
When Anomalocaris was first discovered in 1886 at the Ogygopsis trilobite beds, there was some uncertainty as to what the animal looked like.
