Comments

The codium was anchored in a tide pool before I picked it out for identification. It seemed as though it was growing there. It was a very low tide and I saw a few bunches of codium growing in various tide pools. Let me know if you have any other questions.

Thanks for that clarification, dfitzpatrick, though I have to say I'm a bit dismayed by your news. This will be an interesting site to watch over the next few months/ years.

I have the same question as vitalsleuth - was the fragment you found a floating fragment or a growing, anchored specimen? It makes a huge difference in understanding the importance of your find!

From your point on the map, and the vibrant green color of this piece of codium, can we assume that you found it growing in a tide pool, and not washed up on the beach? I'm particularly curious because reports to date have been of only dead (dark green to brown) washed up codium near Kettle Cove and Crescent Beach. It'd be great to hear it straight from you that it was alive in the pool before you picked it out to photograph.

Thanks so much for looking for codium and contributing such an important find.
