Can't get enough of admiring the Portal. A flock of young Chromis is passing right infront. A wrasse hides upon the cave's floor, and a Diplodus seabream is feeding by the wall on the background.
The cliff itself is overgrown luxuriantly: a funnel-like Padina pavonica, Acetabularia acetabulum in a form of tiny white umbrellas, rounded Codium bursa, Balanophyllia (and Caryophyllia) coralls, forementioned Spongia officinalis and Spirastrella sponges. At the very left a little orange pipe-house of polychaeta is foundable.
A rainbow speck at the very bottom of the pic is nor an optical trick, nor a special effect—it's a ray of sunlight refracted to a spectrum of the rainbow.
