By the bifurcated anterior tentacles and general appearance, this appears to be a species of Mourgona. When first noticed among sand and algae, it had a tint of green that it quickly lost in the later photos. Several specimens were found by Christina Sylvester on the lagoon side of Kwajalein Island at a depth of 1m. Specimens measured about 5mm.
