migrate to tributaries to protect the young from predators, though most spawning activity has been observed in mid-June. During the mating process, one female would begin moving rocks from a suitable area for eggs; afterward she attaches herself to a rock while hopeful males attach to her and stroke her tail attempting to mate. The eggs are then covered with a rock, presumably to shade the young lampreys at birth and to keep any predators from devouring the young. As with most lampreys, the chestnut lamprey only mates once during its entire life and dies shortly after.
