Amnicola limosa – a genus of freshwater snail

Georgian Bay Forever is working with Dr. Kevin McCann of the University of Guelph, and the Canadian Centre for DNA Barcoding to catalogue all the aquatic organisms in Georgian Bay. This will help with measuring the impact of environmental stressors like climate change and human activity such as shoreline development as well as aiding in future conservation efforts, ecosystem monitoring, forensics, and tracking invasives. All the specimens collected and identified will also contribute to the International Barcode of Life , a multi-nation effort to catalogue the world's biodiversity. Here is one example from Georgian Bay's Aquatic Species Library.


    Phylum: Mollusca
    Class: Gastropoda
    Order: Sorbeoconcha
    Family: Amnicolodae
    Genus: Amnicola
    Species: Amnicola limosa

Identification - Linnaean Taxonomy
Belonging to the genus of very small freshwater snails which have an operculum. An operculum is like a a kind of trap door which closes off the shell to protect all the soft parts of the organism inside the shell.

Amnicola limosa

Pretty widespread across North America. They consume diatoms (single cell alga) and other periphyton (organisms that cling to bottom sediments and plants.)

They may be eaten by crayfish and sunfish.
