Neaeromya rugifera
species of mollusc

Neaeromya rugifera is a species of bivalve that inhabits the West Coast of North America.
Description
Neaeromya rugifera is a species of symbiotic bivalve that can be found on the abdomen of Upogebia pugettensis and on the ventral surface of Aphrodita, a genus of polychaete worm. They can attach and detach themselves at will using their byssus. The largest examples of the species were found to be 6mm in length, 2.5mm in height, and 1.5mm in width. N. rugifera do possess teeth, but no chondrophore. One investigation of stomach contents found remains of diatoms and protozoans. Sexual dimorphism is seen as female N. rugifera being larger than their male counterparts. Males can be found to reside in the mantle cavity of females. A 2008 study found no evidence of N. rugifera causing weight loss in U. pugettensis.
Distribution
Neaeromya rugifera is spread across the West Coast, from Kodiak, Alaska, to Punta Rompiente, Baja California.
The public source identifies “Neaeromya rugifera” as species of mollusc. This brief keeps that definition visible, then builds a research path around Neaeromya, rugifera and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Neaeromya rugifera”, the useful work is to connect “species of mollusc” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 14, 2026. The linked authority identifier is Q3787597. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2008.
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.
