Noalda
sp. #2

 
Noalda sp. #2
Maximum size:  3-4 mm.

Identification:  This species has a translucent-cream body densely flecked with opaque white. It has a thin, largely internal shell. A dorsal foramen in the posterior portion of the mantle reveals part of the shell. In contrast to Noalda sp. #1, it has two long "tails," two spiral brown bands on its shell and a head shield that rises to a narrow point on its posterior margin.

Natural history:  Noalda sp. #2 is known from two animals found at moderately exposed sites at 5-6 m (17-20 ft).

Distribution:  Big Island and Maui: may be known from Japan and the Philippines.

Taxonomic notes:  This species is similar to "Noalda sp. 6" in Gosliner, et. al. (2018) but it lacks the yellow spots of that species. However, animals from Japan and some animals from the western Pacific also lack yellow spots. It was first recorded in Hawaii at Kawaihae, Big Island by David Prutow on Sept. 12, 2022.
