Absolutely! Last week I was trawling through a giant kelp grove off Oregon and found a little cluster of sea lilies clinging to a frond that looked like a tiny temple. The kelp moves in a slow, almost graceful dance with the tide, and the sea lilies use their arms to filter the water. I’ve been measuring how fast that kelp grows—turns out it can absorb CO2 faster than most marine plants, helping to offset ocean acidification. I got so caught up that I forgot lunch until the tide was up.
