Hamiota is a genus of freshwater mussels, aquatic bivalve mollusks in the family Unionidae, the river mussels. These mussels are native to North America. They are characterized by their typically small to medium size and often have a smooth, yellowish or greenish shell. Like other freshwater mussels, Hamiota species are filter feeders and play a crucial role in maintaining water quality.
Hamiota mussels face numerous threats, including habitat loss and degradation from dam construction, channelization, and sedimentation, as well as pollution and the introduction of invasive species. Many species within this genus are considered rare, threatened, or endangered. Their conservation is a concern.
The taxonomy of Hamiota and related genera within the Unionidae is complex and subject to ongoing research, with revisions based on morphological and molecular data.
