Hamiota (bivalve)
genus of bivalves
Hamiota is a genus of freshwater mussels, aquatic bivalve mollusks in the family Unionidae, the river mussels.
Taxonomy
The genus was created in 2005 by Roe and Hartfield. It consists of four species that had previously been placed in the genus Lampsilis.
The genus name means "angler", derived from the Greek hamus, meaning "hook". The name refers to the lure by which the species attracts a host fish for their parasitic larvae.
Geography
Species are found in the Gulf of Mexico river drainage in the southeastern United States, including the Mobile, Apalachicola, Ochlockonee, and Choctawhatchee rivers and their tributaries in Alabama, Georgia, Florida, Mississippi, and Tennessee.
Description
Members of Hamiota are small- to medium-sized freshwater bivalves with an oval or elliptical shape, around 45-100mm in length. The shell shape is sexually dimorphic, with males being more acutely pointed on the posterior end. The marsupia (gills) are often asymmetrical. They release their lure and larvae through the excurrent siphon, instead of through pores in the ventral edge of the demibranches like members of Lampsilis.
“Hamiota (bivalve)” enters the record as genus of bivalves. Crown Archives preserves that source wording while asking what Hamiota, bivalve and genus can confirm, complicate or overturn.
Why this record matters
“Hamiota (bivalve)” is worth following because a concise public description often conceals a longer documentary argument. Here, Hamiota, bivalve and genus provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Oct 2, 2025. The linked authority identifier is Q5645323. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2005.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
