2. No clue. 3,000 and 4,000 years
3. Water penny. Not sure on what level of specificity you're looking for, so I'll go with it indicates oxygen-rich and fast-moving water.

1. It is the same thing
2. limited temperature tolerances, high oxygen needs, strong
swimming ability and specialized reproductive strategies to prevent eggs or larvae being swept
away.
3. Both found in lentic communities and can be invasive species and block out sunlight
