- The northern Pacific seastar was first detected in Tasmanian waters in 1986
- By the time removal efforts began, the species was well established in the Derwent River
- The volunteer divers are hoping a regular effort over three to five years could help control it
But while she loves snapping the different creatures she encounters, there is one species that has become an all too familiar sight.
