The Cambrog were a humanoid species indigenous to the Delta Quadrant. Physically they had large ridged brows and were simian-looking in appearance, with their mouths jutting out from their faces.
The Cambrog were know as peaceful and prosperous traders.
One of their colonies located on the planet Praja was visited several times by Neelix in the early 2370s. The colony was decimated by a botanical plague. (VOY comics: "Homeostasis, Part One", "Homeostasis, The Conclusion")
