This was the Merav Vonshak’s simple guess when she posted the above photo on iNaturalist last week. There are currently 29 comments and 11 IDs associated with the observation now, as it set off a flurry of wonder and puzzlement among the iNat community and beyond. It certainly looked like a nudibranch, but...a desert nudibranch? Or perhaps a copepod, centipede or fungus? Folks began posting it on Twitter and Facebook to see if anyone could figure it out.
iNaturalist user @kcclarksdnhmorg came through in the clutch with the correct ID: it was the aquatic sporocarp, or spore-producing part of the Water Clover fern! As its common name suggests, this plant is actually a fern, but closely resembles a four leaf clover. It grows in moist soil or in ponds, and the sporocarps can survive in drought conditions until there is sufficient water for it to grow and split.
A postdoctoral fellow at Stanford who studies ants and other arthropods, Merav had been visiting the park with her family. It was her daughter who “showed me something interesting she found. We looked around the pool and found at least two more of these things...When we came back home I remembered that mystery creature, and decided to upload it to iNaturalist, hoping someone will have a clue. And then the fun began!...I enjoyed reading all the comments and watching it progress. And I was surprised to find out it was a plant after all, with such cool biology.”
“I love looking for creatures and sharing my observations, and iNaturalist is such a great platform for doing just that,” says Merav. “I also enjoy helping others, by helping to ID some creatures, and while doing so I learn so much! I think this is a great tool, but even more importantly, it’s a great community. People are very kind and thoughtful.”
