|Abstract: ||To study the burrowing behaviour and performance of larval sea lamprey (Petromyzon marinus L.), 120 ammocoetes were collected and observed in the laboratory. Burrowing movements of ammocoetes placed in an aquarium with sediments of differing grain size were video recorded. The video was reviewed and, for each larva, the total time spent moving, the number of stops during the burrowing movement, the total time spent stopped and total time elapsed until complete withdrawal below the substrate surface was registered. Smaller ammocoetes had lower burrowing performance than larger individuals, across all substrate types, but the differences were greater in coarser substrates. Additionally, coarser sediment particles increased the time spent on burrowing regardless of larval size.|
