Tartan vole
The Tartan vole was an animal native to Denobula. It consumed Denobulan blood worms by the millions at the start of its reproductive cycle.
During the Multilateral DMA Strategy Assembly in 3190, Captain Michael Burnham noted that the destruction wreaked by the Dark Matter Anomaly may not necessarily reflect malice, just as neither the depredations of Tartan voles on on Denobulan blood worms nor Polyphemus moth caterpillars on crops indicated intent.
