Story: Marine animals without backbones

Researching sea squirts

Researching sea squirts

Queen Charlotte College student John Sunley won a conservation award in 2003 for his investigations into the spread of the invasive sea squirt Didemnum vexillum around Picton, in the Marlborough Sounds. Colonies of Didemnum form thick growths on structures such as boat hulls and jetty pilings. Local mussel farmers fear that the animal could spread into their farms and smother their lines of growing mussels.
