True Nudibranch; Nudibranchia

The Greek word Nudibranch literally means “naked gills” although not all true Nudibranch actually expose their gills. This category covers the majority of the Koh Phangan sea slugs that you can see when SCUBA diving with us.

Featuring long tapering bodies and structures on their backs known as cerata, which are often tipped with stinging cells taken from Cnidarians. (2 Albums, 4 Galleries)

Their gills are hidden and their rhinophores are vertically ridged. (4 Galleries)

Bornella stellifer is our only Dendronotid, but it is well worth the entry. Probably our most spectacular nudibranch; definitely the most interesting.

Our principal Doridacean Nudibranch families are the Chromodorids and the Phyllidids. (5 Albums, 2 Galleries)
