Some kelp I found in a load of sardines - I hadn't seen it before and we're supposed to be documenting bycatch. I noticed that some of it was bright green and other specimens were brown, like this one. Luckily I still have my handy dandy Marine Algae of California from my Marine Phycology class in college, and discovered it's a species of Desmarestia, which sounds familiar, so I must have come across it before. Some of it was green because this type of kelp harbors acids in its tissues - so much so that it will bleach out anything else caught with it (and why some of it looked green).
