[Note Guidelines] Photographer's Note
The Pyjama slug (Chromodoris quadricolor) is one of the most common nudibranchs in the Red Sea. It grows up to 4,5 cm long and you’ll often find them feeding on the Fire Sponge (Lantrunculi magnifica) or "walking" around on sand, stone or coral on search for a meal.

Chromodoris quadricolor can be recognized according to following characteristics :

- the centre of the mantle consists in 3 black bands and 2 bluish bands. This blue colour can't always be seen because it depends on the lighting

- the border of the mantle consists in a broad orange band delimited by one outer and one inner thin white line

- the rhinophores and gills are orange

- the foot looks like the mantle and consists in a sequence of black and bluish bands, and it ends with the orange band and the white line

The bright color of this species is another example of aposomatic coloration, warning predators that it secretes noxious chemicals when disturbed. These secretions come from a series of glands located marginally around the edge of the mantle just below the surface of the skin. In the C. quadricolor case, these mantle glands are relatively large and highly digitate. The glands differ from species to species, in their size, branching and whether the glands form a continuous series or are separated in groups along the margin.

The name 'quadricolor' is due to these 4 colours present in this species.

The picture is taken on 16 meters depth at the dive site Abu Hashish in Hurghada. I've used 1 external Sea&Sea flash. The picture is slightly croped otherwise untouched.
