Two Didemnum patches were found by Rhoda Green near the boat launch north of Shilshole Bay marina in Seattle on the North side of this wall in Sept 2006. The patches are found about 120ft from the start of the pier on the shore. They are in 11 ft Mean Lower Low tide. The rest of the wall as well as the entire south side of this wall had no other Didemnum patches. In March 2007, the patches appear not to have grown much, if at all, in 6 months time. Most of the following photos are by Janna Nichols.
