From the recent REEF PNW Critterwatchers newsletter:Keep your eyes on the stars!
You may have been hearing about the recent seastar dieoff in some areas of BC. There have also been reports of sick or dying seastars in some areas in Washington as well. Scientists are working hard to determine the cause, but need your help.
The Vancouver Aquarium has set up a web form for divers to report both numbers of healthy AND sick-looking seastars.
You can find the link to report what you observe here: http://www.vanaqua.org/act/research/sea-stars
Seastar expert Neil McDaniel, (website http://www.seastarsofthepacificnorthwest.info
) has graciously allowed us to post his photos showing the progression of the disease over a short period of a few weeks. This can give you an idea of what you're looking for. View Neil's photos here: http://pnwscuba.smugmug.com/Diving/Seas ... g-Syndrome
Remember, the Vancouver Aquarium wants to know the location of both healthy AND sick-looking seastars. http://www.vanaqua.org/act/research/sea-stars
Feel free to pass this on to your dive buddies, club members, and other interested divers willing to help!
