Zebra and quagga mussels are two invasive mollusk species that colonized the Great Lakes area of North America.  They disrupt the ecology of areas they colonize by out-competing native mussels.  Students learned about where these invasive mussels are from and how they arrived here and spread.  They also learned about their lifecycle, the similarities and differences between the two species, problems associated with the species, and how biological adaptations give them an advantage to colonize new areas. Techniques used by natural resource agencies to combat these invaders were also discussed.

The students were very interested and informed about zebra and quagga mussels, as they have been studying them in their classroom.  Approximately 25 students attended the presentation.
