Tylodina sp. 2 (undescribed)

This shelled sea slug belongs to the Umbraculoidea, or umbrella shells. Original thought to be related to side gilled slugs (the Pleurobranchoidea in the Notaspidea), because of the placement of the gill situated on the right side of the body, they are now been shown to be distinct, because of the external shell.

Members of Tylodinidae have a limpet-like shell that covers the body completely. Most species are known from temperate, cold water, regions. This is one of the exceptions.

The body is yellow all over. The cap-shaped shell can have varying degrees of brown. This was one of the almost 600 species found in Anilao during this year's Slugfest at Crystal Blue Resort Crystal Blue Resort.
