Several horizontal sections on this infographic show the following:

• slender barbel at the corner of the jaw and a snout that projects beyond the mouth
• large eyes on the upper half of the head
• large minnow that can reach around 230 mm

The next section lists threats, including:

• habitat degradation
• sediment and nutrient loading
• invasive species
• contaminants

A further section notes that Ontario populations found in the Great Lakes Basin are limited to Lake Erie and Lake St. Clair, the lower Thames River, and the extreme southern point of Lake Huron.

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:

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