Pleistacantha is a genus of crabs in the family Oregoniidae.[2] It is found in the Indo-Pacific and Europe.[3][4][5] It is found in a depths of 129–530 ft (39–162 m).[citation needed]
Description
[edit]Pleistacantha are medium to very large crabs whose carapace is orange to reddish-orange and whose walking legs are reddish-brown to reddish-white.[6][failed verification] Its walking legs are long, slender and decreasing in length posteriorly.[7][failed verification]
Taxonomy
[edit]Pleistacantha was described by zoologist Edward J. Miers in 1879.[1] Its name is derived from the Greek roots pleistos (πλεῖστος), a superlative meaning "many", and acantha (άκανθα), meaning "spine".[1] In 2013, evidence that the family Inachoididae was not monophyletic prompted carcinologists to move Pleistacantha and several other genera into the family Oregoniidae.[8]
