Classification provided by the World Register of Marine Species (WoRMS). [140272<\/a>]<\/p><\/div>Description
\n<\/strong>Body elongated and narrow, small sized (about 5mm) and coloured brown, with a large number of brown or golden yellow surface spots, less dense in some irregularly distributed areas, which acquire a dark -almost black- appearance. It has up to 36 cerata arranged vertically in three pairs of curved crests located contiguously from the back of the rhinophoral sheaths to the caudal region, forming a characteristic ripple on each side of the notum. In front of the first pair of dorsal crests there are two small cerata facing outwards. In the dorsal crests the larger cerata correspond to those that are in the most dorsal position. The cerata are digitiform, wider at their base, with one or two constrictions and with a rather large apex. The cerata coloration follows the pattern of the body, but the amount of golden scores is smaller than in the rest of the body. The frontal veil is rounded and has two processes aimed at each side of the body, the shortest of which is in the inner position. The rhinophores are elongated (a quarter of the total length of the body) and have 8 to 9 inclined lamellae. The apex of the rhinophores extends slightly beyond the apical end of the rhinophoral sheaths. There is a small ridge on the back of each rhinophore. Rhinophoral sheaths are high and have two constrictions that favor a very characteristic central thickening. The rim of the rhinoform sheath is cup-shaped and has 6 or 7 processes similar to the cerata, with one or two constrictions, a broad base and a slightly bulging apex. Dorsally, in the cephalic region, there is a small tuberculate ridge arranged longitudinally that continues between the rhinophores to the beginning of the dorsal crest. The raised and wrinkled-looking pericardial area is located between the first and second pair of dorsal ridges. There could be a series of dorsal tubercles between the second and third dorsal ridge. The forefoot is broad, with two marked lobes, while the back of the foot is short and tappered. The genital pore is on the right side of the animal, between the rhinophore and the first dorsal ridge. The anus and renal pore are not visible in the studied specimens.<\/p>\n

Biology
\n<\/strong>The specimens of this dendronotid are extremely cryptic on the substrate in which it is found: calcareous stones of sedimentary origin. It has been found in the intertidal zone near the Kirchenpaueria pinnata<\/em> and Ventromma halecioides<\/em> hydroids from which it is supposed to feed, although it has not been possible to observe this fact (Garc\u00eda G\u00f3mez et al., 1990). The specimens found in Croatia were found 20 meters deep on the algae Cystoseira sp.<\/em>\u00a0close to hydroids of the Plumularioidea superfamily (Trainito et al., 2017). Its ability to live unnoticed is excellent because it allows small particles of the sediment to adhere to the cerata and rhinophores as part of its camouflage.<\/p>\n
