The body is slender,\u00a0slim and coloured dark blue, but the characteristic trait of the species are the yellow lines present on the back and sides of the body. Among these yellow lines there is a\u00a0submarginal one, bordering the entire dorsum,\u00a0and a central dorsal one flanked by 1-2 lines on both sides which may be continuous, discontinuous, and join or not to\u00a0each other. The central and lateral yellow lines join ahead of rhinophores, also surrounding the base of the rhinophores and the branchial sheath. Ortea et al. (1995) have studied the color and variability of this species suggest that the greater the size of the animal, the more complicated the design of the yellow lines. Some specimens\u00a0of appreciable size may be\u00a0somewhat depigmented, having a light blue coloured body. The back usually has many\u00a0elongated turquoise spots aligned between the submarginal and lateral yellow lines. The flanks of the body also have yellow or white longitudinal lines and elongated turquoise spots, as in the back. The rhinophores are dark blue and have 15-18 lamellae in larger animals. Rhinophores’ lamellae are connected\u00a0in the rear side\u00a0forming a white\u00a0zigzag line. The gill is composed by\u00a08-10 semitransparent, dark blue leaves with an iridescent white rachis. The foot is narrow, blue, somewhat lighter coloured on the leading edge. The mouth has two short labial palps.<\/p>\nBiology\n<\/strong>This is a relatively common species throughout most of the year in all kinds of rocky substrates, from the intertidal zone down to 30-40m depth; it has also been captured at about 100 m depth in commercial trawl fisheries. It is also common in meadows of Posidonia oceanica<\/em> (Templado, 1984). It has been said that feeds the sponge Dysidea fragilis<\/em>, from which it obtains the longifoline, a furanosesquiterpenoid which is its main defense alomone; it builds up in the animal’s\u00a0mantle glands (MDF’s), present in the mantle edge, both at the height of the rhinophores as in the post-gill area (Garc\u00eda-G\u00f3mez et al 1991;. Fontana et al. 1993; \u00c0vila, 1993). The spawn\u00a0consists of a semitransparent ribbon\u00a0wound in a one turn and half spiral, containing about 400 orange or yellowish eggs of about 350 microns in diameter. The development is direct, without free veliger larva stage (Gant\u00e9s, 1962).<\/p>\nEtymology<\/strong><\/p>\n\nVillafranca<\/em>.

Under the direction of the CNRS it is home to three scientific research laboratories (oceanography, marine geosciences and cell biology), with about 150 working people.<\/li>\n<\/ul>\nDistribution\n<\/strong>Felimare villafranca<\/em> is distributed from the Atlantic coast of Brittany, the Atlantic coast of Morocco and all around the Mediterranean, both in the eastern and western basins. In the Iberian Peninsula it has been found in all coastal areas, also in the Balearic islands. Its absence from the Canary Islands, Madeira and the Azores may be due, as indicated by Ortea et al. (1995), to the embryonic direct development type, with no larval stage that allows planktonic dispersion. In the Catalan coast it has been cited in numerous locations in the Costa Brava, also in Llavaneres, in the port of Tarragona and in the Port of l’Estany (Tarragona). <\/div>\n
