Description: Aquatic Species at Risk, Fawnsfoot (Truncilla donaciformis

SARA Status: Endangered

Several horizontal sections on this infographic show the following:

The logo for DFO in the top left and bottom right corner of the infographic

Two illustrations of the Fawnsfoot (Truncilla donaciformis), with the first showing the following aspects labelled:

• the beak is full, central, and raised slightly above the hinge line
• yellow to greenish in colour and has dark green rays that are broken into v-shaped markings

The second illustration shows the following aspects labelled:

• triangular to oval in shape with a bluntly pointed end and a rounded end
• small mussel reaching approximately 25 mm in length

The next section lists threats, including:

• invasive/introduced species/disease
• contaminants
• habitat degradation
• sediment and nutrient loading

A further section notes that Fawnsfoot is currently present in the delta area of the St. Clair River, and the Sydenham, Thames, and Grand rivers. One unusual record exists in Muskrat Creek (Saugeen River); however, this is likely the result of an introduction, since no other specimens have been detected there.

To the right of the infographic, a map of Ontario shows, by an overlaying rectangle, where the related population is found. Another map on the left of the infographic shows a magnified view of where the population is found by use of splotch markings, with lakes Ontario, Erie, and Huron labelled.

A final section on the infographic notes that activities in or near water can harm aquatic species, and lists what you can do:

• report any invasive species sightings to DFO
• prevent contaminants from entering water
• keep your shorelines natural
• protect sensitive habitat; contact DFO before doing any in-water work
