Pinnoctopus rapanui, or the rapanui octopus,[3] is the only endemic octopus species in Rapa Nui (or Easter Island).[4] It was first described by Gilbert L. Voss in 1979[5] as Octopus rapanui.[6]
Description
Pinnoctopus rapanui is large and muscular, with a mantle length of up to 115 millimetres (4.5 in) and a total length of up to 550 millimetres (22 in). It has scattered rough tubercles across the body.[7] The arms are 3.5 to 4.5 times the length of the mantle, and have two rows of suckers each. P. rapanui is cream-gray with a darker purple hue on its dorsal surfaces.[8] Its most distinctive feature is a "straight, out-turned" rostrum.[9]
Distribution
Pinnoctopus rapanui is subtropical[3] and only known in Rapa Nui.[8] It is benthic,[3] and found at depths of zero to four metres (0 to 13 ft).[8]
Use by humans
Pinnoctopus rapanui are fished for food in Rapa Nui, and make up 0.6% of subsistence fishing catch.[10]
