Whidbey Island Critters
Re: Whidbey Island Critters
It was a very interesting week at Penn Cove, Whidbey Island.
It is still a mystery what caused the one week long massive stress event which affected many of the critters inhabiting the muck there. Many of the affected species don't come up into the world above sand and show only parts of they bodies if they do. It all started on Thursday September 18th when I finished my weekly survey of the Sea Star Wasting Syndrome which almost wiped out the zillions of Mottled stars which used to live under the wharf. With lots of air left, I decided to explore new territory.
At one spot I found some Burrowing Brittle stars which normally show only their arms, waving them above the sand. Here there were out in open. And as I continued swimming, more and more of them appeared. Also found Red Sea Cucumbers in very bad shape. Something was wrong. And so started my obsession with Penn Cove, making daily visits and contacting scientists, looking for answers. It is still work in progress, even if the marine life there returned to normal, most of the affected critters disappeared under the muck, except the cucumbers...
My first blush was that it was caused by Oxygen depletion, caused maybe by the great die-off of the sea stars which left the area under the wharf covered with white microbial mat, combined with the hot weather we had and rather poor circulation of the water in the cove. Especially after the stormy weather we later experienced coincided with the end of the stress event. At the peak of the crises, there was a white layer of water on top of the affected area where the visibility was less then three feet. It was not possible to even estimate the area of the problem area, that would require a boat and much more effort. Plus I didn't even know what I am dealing with. Nearby Mussel farm did not issue any warning about pollution.
Here are few samples of what I found there...

Re: Whidbey Island Critters
OH no...this is not good. I hope it was just an isolated event in an isolated location and doesn't spread. :(

It does look like it was just that - isolated event.enchantmentdivi wrote:OH no...this is not good. I hope it was just an isolated event in an isolated location and doesn't spread. :(
But sadly spectacular one .

Re: Whidbey Island Critters
Hi Jan,
That's a nasty looking event! It does suggest a few questions:
1. Did you see signs of distress in any animals that don't live in the sediment (fish, crabs, etc.)?
2. In the aftermath did you see any indication that the storm you mentioned had disturbed the sediment?
3. Also in the aftermath; have the distressed animals reburied themselves or are there corpses lying around?
4. Did you send your observations to Ron Shimek? He's something of a specialist in unconsolidated sediment (sand & mud) habitats.
Good to hear that the event seems to have passed!
Sedimentally yours,
Alex

1. No fish sighted, it is rather barren sandy/mud plain - Cancer gracilis doing OK, Serpula columbiana worms also look healthy. so did the few slugs I found.
2. The winds were not big enough for that, maybe mix the water but not the bottom. I don't know.
3. Yes, Clams and most of the brittle stars seem to be back in hiding, as did all the worms, unless something ate them all up. Again, I don't know for sure, all I can tell, is that the abundance of species I never seen before were all gone on my last visit there.
4. And yes, I keep Ron informed at all times, since he sure knows more about all this then I ever will. Great guy.

Re: Whidbey Island Critters
Thank you Lynne,
I continue posting critters which the mystery event at Penn Cove brought up from the unseen world of muck,
probably not something most divers care for. Worms don't possess the cute factor of fish and crabs, but
since I have hard time to add new species of those, here are the inhabitants of MUCK

Re: Whidbey Island Critters
I can't speak for anybody else, but I find all the critters in our home waters fascinating, and I hop on here every morning eagerly hoping to learn something new from you. So please, whether crabs, fish, worms, mites, pet rocks released into the wild, whatever, keep them coming!

Jan: The photo of the brittle stars brings to mind the prints of Gustave Dore that you featured before, or even a drawing by Escher. To quote Spock, "Fascinating."

Re: Whidbey Island Critters
Last Thursday I made a dive at Deception Pass and found couple of Red Sea Cucumbers showing
signs of some kind of disease. I am not saying it is the same malaise which hit the sea stars, but
so far I did not see anything like this before. Also it was strange that 99 % of the cucumbers there were not
feeding at all. Worrisome ...

I did find some data on internet taken at the nearby commercial mussel farm, I am still hoping that somebody
will give me some idea what happened. I have to admit, it is above my pay grade ...
