Salaria basilisca is a species of combtooth blenny found in the Mediterranean Sea near Tunisia and Turkey, also in the Adriatic Sea. This species reaches a length of 18 centimetres (7.1 in) TL. It is found among seagrass, sometimes where there is a rocky substrate. The male guards the eggs produced by several females. They are protogynous hermaphrodites with individuals being females while young changing to males later.

Training day of the photo contest.
The photo contest is about the amount of fish. I couldn't resist to photograph also other species. It was in freediving and I never did a course for it. I had a hard time also 5 hours in a row in the water. But a lot of fun!
