Onykia robusta
species of mollusc
Onykia robusta, also known as the robust clubhook squid and often cited by the older name Moroteuthis robusta, is a species of squid in the family Onychoteuthidae. Reaching a mantle length of 2 m (6.6 ft) it is the largest member of its family and one of the largest of all cephalopods. The largest specimen with reliable catch data was found in the Bering Sea, a male with a total length of 3.72 m (12.2 ft) and weighing 41.73 kg (92.0 lb). The tentacular clubs are slender, containing 15–18 club hooks. Arms of the species contain 50–60 suckers, and grow to 90–100% of the mantle length. It is found primarily in the boreal to Temperate Northern Pacific.
Size
O. robusta can reach up to 2 m (6.6 ft) in mantle length. Nesis gave a maximum mantle length of 2.3 m (7.5 ft), however Roper and Jereb wrote that "this might be in error"; it commonly grows up to 1.6 m (5.2 ft) in mantle length. If the tentacles are measured from the tip to the tip of the mantle, Glaubrecht, M. & M. A. Salcedo-Vargas provided the maximum estimated to be 4–6 m (13–20 ft) in overall length. This species weight is up to 50 kg (110 lb).
Begin with the source’s own compact description: “Onykia robusta” is species of mollusc. The dossier treats that line as a proposition to test through Onykia, robusta and species, not as a finished interpretation.
Why this record matters
The phrase “species of mollusc” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 15, 2026. The linked authority identifier is Q2934325. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
