The East Asian common octopus is adapted to a benthic life at the bottom of the sea.

Revision as of 22:17, 14 February 2022

Octopus sinensis (commonly the East Asian common octopus) is a mollusk belonging to the class Cephalopoda. Octopus sinensis is a well-known shallow-water benthic octopus species found in the coastal, temperature waters of South Korea, China, and Japan,[1] closely related to the Atlantic and Mediterranean common octopus, Octopus vulgaris.[2] Because of the morphological similarities, O. sinensis was considered synonymous with Octopus vulgaris until 2017.[2][1][3] Octopus sinensis are carnivores that prey upon on many shallow-water animals such as crustaceans and mollusks.[4][5]

The East Asian common octopus is adapted to a benthic life at the bottom of the sea. Octopus sinensis has long arms with many suckers used for catching prey, a mantle without a rigid skeleton, which allows them to inhabit and hunt in small spaces and crevices in the seabed, horizontal pupils, and versatile skin with ability to change colors and camouflage themselves with the sea floor.[6][7][8] Compared to O. vulgaris, O. sinensis have a broader mantle and relatively shorter arms with fewer suckers.[1]

Physiology

The East Asian common octopus goes through a several-week planktonic phase, in which they are floating in the open sea.[9][10] This occurs early in their development prior to their permanent benthic habitation, similar to many benthic octopus species.[11][12][13] During their planktonic phase, the morphology of the East Asian common octopus is similar in morphology to the juvenile and adult life forms and is termed the paralarval stage after the octopus hatches.[14] The paralarvae have certain characteristics that differ from the adult stage, which allow it to thrive in the planktonic phase, such as transparent musculature, circular pupils rather than horizontal ones, a proportionately larger mantle (2.1 mm in length) and shorter arms with fewer suckers (three to four on each arm), and a finely toothed beak.[6][9][14][10][11] However, not much is known about the early life stages of the East Asian common octopus in their natural habitat due to their cryptic and allusive behavior.[15][10][16] Recent studies suggest that transition from the planktonic stage to the benthic settlement is quite complex in O. sinensis and takes them a significant amount of time.[16][17]

Cultural Importance

Not until 2017 was O. sinensis named a separate species from O. vulgaris on the basis of molecular and morphological features.[2] Both species are commercially important food sources in China and it is important to delineate the two species for sustainable and fisheries management.[1][18] Due to its rapid rate of growth and its high commercial value, O. sinensis is of particular interest in aquacultural cultivation[19]. There have been several studies since the 1960s that have attempted to rear O. sinensis and O. vulgaris aquaculturally with little success.[20][21][11]
