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.

• 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.
