ID suggested by Greg Jensen. I assumed it was L. Leucomanus but based on the extension of black on the merus of the claw, and the the general claw structure, I believe frontalis is the correct ID. Tiny crab flipped under a rock, and was found crawling on the underside of the rock when exposed. Lifer regardless of species. If I’m not mistaken this is the first case of this species on iNaturalist

Small clumps of orange eggs observed. Polychaete worms were numerous so perhaps these are from them.

This observation is a part of the long-term monitoring efforts of Gustav Paulay and his team at FLMNH and Friday Harbor Labs.
Although this observation also falls within the boundaries of the MarineGEO iNaturalist umbrella project (which is an ongoing collaborative work between MarineGEO and the Tennenbaum Marine Observatories Network, the Florida Museum of Natural History, the Smithsonian’s National Museum of Natural History Museum, and our network partners), this is not from a MarineGEO specific campaign.

These are its markings, not coralline algae! Clearly a juvenile, but what?
About 1/3" across carapace. Clinging to drift seaweed.

- from marine sample (sand and water), collected at shoreline
- objective(s) (x 10): images 1-4, 40x; images 5-14, 100x
- video on Vimeo
- ID: ELPB-LGT40
- Adult Emerita analoga observed in the area where this sample was collected.
- Could not find images of zoeal stages of E. analoga. However, these specimens closely resemble the first zoea of E. emeritus, as seen in Fig. 1, page 446 of the below reference. And, since E. analoga is the only Emerita found in (Southern) California, it seems reasonable to suggest that these are E. analoga.

On eel grass. No idea what this might be but none of the other grass had these on it.
