| You've heard of the zebra mussel, and you may have heard of its cousin, the quagga mussel. |
| The quagga is a placental mammal, a group also called Eutheria by scientists. |
| I can if you want technical details later on how the zebra and quagga mussels are promoting conditions to enhance this bacterial growth. |
| The first DNA to be extracted from an ancient specimen was from 150-year-old tissues from the quagga, an extinct relative of the zebra. |
| We have wiped out more species than I can name, from the dodo to the moa to the quagga to the thylacine. |
| Non-indigenous zebra mussels and quagga mussels have severely decreased native mussel populations. |
