Nudibranchs are carnivores grazing on algae, anemones, barnacles, corals, sponges and also on other nudibranchs. The two highly sensitive tentacles, called rhinophores, on the top of their head locate their prey. The alluring colours of nudibranchs come from the colouring of the food they eat. Some nudis retain foul-tasting poisons of their prey and then secrete them as a defense against predators.

Black-faced Blenny - Tripterygion delaisi
Italiano - Peperoncino giallo
T.delaisi inhabit depths between 3 - 40m. It prefers dark areas hidden between rocks and under overhangs.
They are territorial breeders. The males are responsible for taking care of the eggs.
Nudibranch Mating
Mating occurs head to tail through a genital aperture.
All nudibranchs are equipped with both male and female reproductive organs, each fertilizing the other, and both producing eggs.
Peacock Worm - Sabella pavonina
At first sight these little animals look like plants, but they are in fact worms.
The worm lives inside the tube formed from mud, sand particles and mucus. Protruding tentacles extend outwards and filter feed on passing particles. When disturbed the tentacles quickly retract into the tube.
