Octopus minor
species of mollusc
Octopus minor, commonly known as the long arm octopus or the Korean common octopus, is a small-bodied octopus species distributed along the benthic coastal waters bordering China, Japan, and the Korean Peninsula. It lives at depths ranging from the sea surface to 200 metres (650 feet; 100 fathoms). O. minor is commonly found in the mudflats of sub-tidal zones where it is exposed to significant environmental variation. It is grouped within the class Cephalopoda along with squids and cuttlefish.
O. minor carries cultural and economic value in the countries in which it is found. It is important commercially to the fishing communities in Korea, where it is known as nakji, and contributes to the $35 million octopus industry. It is a Korean seafood, commonly referred to as nakji (Korean: 낙지). The octopus is served both cooked and raw, and is often a snack during sporting events.
There have been multiple findings concerning the physiological makeup of O. minor. It has been shown to host a dangerous parasite, while also demonstrating the ability to adapt its morphology to a wide range of environmental conditions.
The public source identifies “Octopus minor” as species of mollusc. This brief keeps that definition visible, then builds a research path around Octopus, minor and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Octopus minor”, the useful work is to connect “species of mollusc” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 8, 2026. The linked authority identifier is Q76565. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
