Rhinophores (literally “nose-bearing”) are the ‘horns’ atop a nudibranch. They are olfactory organs able to sense chemicals dissolved in the water. Their intricate structure allows for a very large surface area over which to … smell.
Thuridilla sp. by Samantha Craven
Thuridilla is a genus of sacoglossan sea slugs, shell-less marine opisthobranch gastropod mollusks in the family Plakobranchidae. They are not nudibranchs, but are often confused for them.

Nudibranch Eggs (possibly Hypselodoris sp.)
After their freaky hermaphroditic mutual sperm swap, both nudibranchs lay seperate egg ribbons. In most cases these are laid directly on the species food source. The shape, colour and design is often characteristic of the specific group or Family.
Most are toxic to deter predation. But then we don’t really expect any less from nudibranchs, do we?
Wavy-lined Bubble Shell (Micromelo undata)
The name bubble shell is a little misleading as not all species have shells. Some do have strong shells they are able to retract into, while others have very thin shells or none at all.
Komodo ‘11: Day Four: Deadman’s Island
Great wall dive. One of the first things spotted were these two HUGE Pleurobranchs.
Pleurobranchus is a genus of side-gilled slugs [Suborder: Notaspidea]. Their anatomy is characterized by a single, external ctenidium (respiratory apparatus) on the right side, rolled rhinophores, and a flattened shell.
I have no idea what this species is. Help very welcome. Any ideas?
