Get to know the five beautiful members of the Gilt Darter species complex! 🐟

"Ok, but what is a species "complex"?!?" you ask? It's a group of closely related species where typically some new species have been recently described. 🧬

Get the scoop on our latest Fish of the Week podcast episode, where we dig into what makes a species a species and how describing biodiversity is important to conservation. Tune into new episodes every Monday on our FWS website or wherever you get your podcasts! 🎣
