What is the typical lifespan range cited for an adult Zebra Mussel?
Answer
Four to eight years
The lifespan of an adult zebra mussel is relatively constrained compared to some other bivalves, generally ranging between four and eight years. This duration is long enough for them to reach maturity and reproduce extensively, but short enough that continuous recruitment is necessary to maintain high population levels. The growth rings and concentric wrinkles visible on the shell surface serve as physical markers that track the organism's development over this specific time frame.
