Pollicipes polymerus – Nakwakto variety of goose-neck barnacle-The Race Rocks Taxonomy

Image by Garry Fletcher,September 7, 2011
This is the first image taken of this variety of gooseneck barnacle at Race Rocks. On the tidal energy generator which was removed in 2011. Two clumps of these barnacles were collected from a join in the housing materials. In Lamb and Hanby, Marine Life of the Pacific Northwest, they state the following:“—Nakwakto goose-neck barnacle, a large and colourful variation of the goose neck barnacle found inlNakwakto Rapids, Slingsby Channel, BC. The glorious red colour is actually the hemoglobin in the barnacle’s blood. The blood is obvious in subtidal specimens like these which do not have black pigment that which protects the sun-exposed populations inhabiting shallow or intertidal zones. Familiar to an ever-increasing number of recreational divers, the unique and isolated population must be preserved via a No-Take Marine Protected Area.”

The weekend was not as busy as I had expected, however there were hundreds of people here from sunrise to sunset. The general public has shown increased knowledge or respect for the reserve guidelines and the majority of the traffic was sight-seers. I am pleased to report there were 0 marine mammal disturbances yesterday. However, rental boats with weekend-warrior fishermen continue to threaten the Race Rocks ecosystem. Pedder Bay Marina continues to respond to reports from the Eco-Guardian concerning illegal fishing by their customers. There were 6 boats poaching in the reserve yesterday, half belonging to Pedder Bay Marina. There were 0 visitors to the island today.
