As my French name suggests, my body can show signs of metallic blue reflections which can be seen especially when I'm out of the water. As most of my cousins, my body is slightly elongated and I have a rather pointed head. To differentiate me from the others, you can note the black marks between the last spines of my dorsal fin, these are unique to my species!
Our mating season occurs either in spring or summer. Our eggs are adhesive! They are therefore deposited on branches under water, tree trunks or submerged roots.
We are very common in Québec, often caught in large numbers.
