Haikoucaris is a genus of megacheiran arthropod that contains the single species Haikoucaris ercaiensis. It was discovered in the Cambrian Chengjiang biota of China. [1]
Haikoucaris measured about 38 mm in body length. [1] The elongated body compose of a semicircular head shield, 13 trunk tergites and presumely a short, spine-like telson. [1] [2] The head possess a pair of unstalked eyes, a pair well-developed great appendages, as well as 3 more appendage pairs of unknown detail. [2] Each of the great appendage consists of a 2-segmented peduncle and a 3-segmented claw. [2] Each of the trunk segment possess a pair of biramus appendages that each comprising a leaf-shaped exopod and a possibly 7-segmented endopod. [2]
Haikoucaris may have been a predator, with its great appendages and exopod suggested to be used for hunting and swimming respectively. [2]
Within megacheirans, Haikoucaris is generally accepted to be a member of the clade Cheiromorpha alongside Yohoia and Leanchoiliidae. [3] [4] [5] [6]
