- Bucchich's goby (Gobius bucchichi)
- Dusky sweeper (Pempheris rhomboidea)
Another immigrant from the Red Sea. Seen in caves in groups. Previously misidentified as Pempheris vanicolensis; genetic analysis has confirmed that the Mediterranean Pempheris is Pempheris rhomboidea (thanks to Francis Pantus for the update!)
- Pearly razorfish (Xyrichthys novacula)
Able to dive into sand and bury themselves if they sense danger.
- Comber (Serranus cabrilla). A small (~20-30 cm long) member of the grouper family
- Cardinalfish ( Apogon imberbis)
Seen in groups in caves or large holes. They feed on plankton at night.
- Hyper calcified sponge (Petrobiona massiliana)
The small white blobs next to the markers are the sponges. This is a very rare "living fossil". It was first found in dark caves near Marseille and it was determined to be the only living species of a group of sponges previously known only as fossils. It is now being researched as its skeleton holds a climate record that might be of use in understanding changes in the marine environment and possibly climate change.
- Kidney sponge (Chondrosia reniformis) reproduction
Here you can see how the sponge reproduces asexually: globules of the sponge dangle from the parent sponge till finally reaching another surface where the sponge will continue to grow, in essence cloning itself.
- Small sea hare (Aplysia punctata)?
Identification not definite, but I'm fairly certain this is a species of sea hare.
