This appears to be what Gosliner et al (2018) call Nakamigawaia sp. It also looks like a species of Melanochlamys. At times they are commonly found crawling on sand in or near Halimeda patches on a sandy lagoon slope at depths of 8 to 10m. We can, however, go for long periods without seeing any. The first one we found, figured below, was on 11 February 2008. The shot of the tiny animal was taken with a digital microscope with limited depth of field.
