We took an underwater photography trip to the Philippines in December 2016.
NOTE: We love nudibranchs, but we are not experts on these animals. If you find something we have misidentified or can identify something we couldn't, email us and we will correct it.
Nudibranchs are soft-bodied marine gastropod molluscs that shed their shells after their larval stage. "Nudibranch" means "naked gills". There are two main kinds of nudibranchs, aeolid nudibranchs and dorid nudibranchs.
Aeolids have cerata, no bronchial plume, no mantle, and may have zooxanthellae. Lacking separate gills, respiration takes place thorough their cerata.
