Thuridilla hopei_October 2024
(Canon EF100,1/200,f14,iso100)
Thuridilla hopei. Often mistaken for a nudibranch, it is a sacoglossal opisthobranch without dorsal appendages. It can only be spotted with a keen eye, on the rocky seabed a few meters deep. Rarely exceeds 2cm in length.

Bavosa Cervina( Parablennius incognitus)_Oct 2023
(Canon EF100,1/200,f8,iso100)
We often don't see them, but a thousand eyes watch us while we swim or dive with our sophisticated equipment that makes lots of bubbles. Like this friendly hermit crab which I found on a rock a few meters deep.

Pair of Cratena peregrina nudibranchs_August 2024
(CanonEF60, 1/200,f18,iso100)
Flabellina has a specialized diet based on hydroid polyps. Just look for the colonies of these polyps (similar to small bushes often positioned on the tops of rocks to catch current) to find it more easily!_June 2024
(Canon100, 1/200,f/18,iso100)
Watchful eye that of the Mediterranean Hermit Crab, always careful to protect abdomen, which is not covered by a rigid cuticle, inside the shells of gastropod molluscs that it finds abandoned_August 2024
(Canon100,1/200,f14,iso100)
Contrasts make a photo more interesting. Apart from the black of background,the orange with purple tips of "cerata" compared to the white bodies plays in favor & composition of two Cratena with different focus.July2024
(Canon 100,1/200,f18,iso100)
Elysia shy, white with red dots on body,head and rhinophores. It is characterized by a green color bands produced by the chloroplasts that it retains in the cells of digestive system_June 2024.
(Canon 100,1/200,f14,i.100)
The Ischian flabellina is a close cousin of the lilac one with which it is confused. The epidermis of the Ischia cerati is transparent and thus allows a glimpse of the bright orange ducts of the digestive gland_ June2024
(Canon 100,1/200,f18,i.100)
Since July here in Sicily you can see many more Cratene than before, close together, intent on laying eggs a few meters deep, let's say around fifteen meters. An excellent time to shot some of them in pairs._July_2024
(Canon100,1/200,f18,iso100)
Cratena nudibranch. A Cratena leaps to reach another twig of hydroids on which to feed and lay its eggs. Taken in July 2024
