Described as a distinct species in 2017, the Blueface Darter has intrigued scientists for decades. Initially grouped within the Bandfin Darter species complex in 1995, this darter stood out early on as unique due to its physical and ecological distinctions (Kuhajda & Mayden 1995). However, its formal recognition as a new species only recently solidified its place in the records of ichthyology.

Blueface Darters are restricted to less than 12.5 miles across two stream systems in northwestern Alabama. Despite its limited range, one particular area that it inhabits is a biodiversity hotspot, home to roughly 100 different species of fish!

As one of Alabama’s rarest fishes, the Blueface Darter faces numerous challenges including habitat disturbances and invasive species like the Weed Shiner. Past surveys have reported this species at only 20 sites between the two river systems that it inhabits. Given these vulnerabilities, establishing a monitoring program to track its abundance and distribution is critical for its conservation (Shepard et al. 2009; Phillips & Johnston 2004a, 2004b).

We’ve had the joy of observing the Blueface Darter’s unique reproductive behaviors firsthand. These fish are prolific and somewhat unconventional spawners, earning the nickname “Easter eggers” for their habit of scattering eggs across all sorts of hard surfaces. From rocks to submerged wood, their adaptability in egg placement reflects their resourcefulness and the dynamic nature of their habitat.

Working with this species marked our second experience with a snubnose darter (Ulocentra) species. This project highlighted just how unique and fascinating each darter species can be, as we discovered significant differences between the Blueface Darter and the Warrior Darter, which we had worked with in 2004.

Unlike the Warrior Darter, whose larvae are highly pelagic and easy to collect passively, the Blueface Darter’s larvae presented an entirely different challenge. Their behavior required us to adapt our approach, going in to carefully collect and incubate their eggs. This distinct life history trait might hold the key to their survival in a dynamic environment. By securing their eggs in more stable microhabitats, the Blueface Darter ensures that heavy rain events don’t wash away an entire year’s worth of offspring—a vital adaptation for a species that thrives almost exclusively above a falls.

Working with the Blueface Darter provided us with invaluable insights into the diversity of strategies that this species uses to survive and flourish. It’s a reminder of nature’s resilience and ingenuity, inspiring us to continue learning and adapting in our conservation efforts.
