- Small triplefin (Tripterygion melanurum)
Quite common and relatively easy to spot thanks to its distinctive colouring, though it is only a few centimetres long (never more than 6cm!)
- Common octopus (Octopus vulgaris)
Octopus mostly hide in holes or under rocks during the day as they are nocturnal feeders. However they are quite inquisitive so will put their heads up to see what is happening as a group of divers goes by (see inset photo)! They pull rocks and bits of shell in on top of themselves to cover the entrance to their holes.
- 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.
