Classification provided by the World Register of Marine Species (WoRMS). [585313<\/a>]<\/p><\/div>Taxonomic note<\/strong>: In the last revision of the genus (Millen & Gosliner, 1985) the authors indicate that the situation is unclear. Aldisa smaragdina<\/em>\u00a0is believed to be a synonymous with the former\u00a0Aldisa binotata<\/em> Pruvot-Fol, 1953. The problem is that the original description of A. binotata<\/em> is poor, with no information of its anatomy. The unique specimen on which the description was based is lost, so it can not be studied. So European researchers use the name Aldisa smaragdina<\/em>, as there is no consensus on whether Aldisa binotata<\/em> can be recognized.<\/p>\n

Description
\n<\/strong>The body is dorso-ventrally flattened, up to 30 mm of length and deep red colored. The mantle\u00a0is covered with small tubercles. There are two large dark oval spots located between the rhinophores and the gill. There is also a\u00a0quite faded whitish band on each side, located right\u00a0behind the first dorsal spot. It has two lamellated rhinophores, with few lamellae arranged almost vertically, protected by tuberculated rhinophoral sheaths. The gill consists of 5 reddish, white tipped gill leaves, protected by a crenulated sheath (with a series of crested mantle projections). The oral tentacles are short and blunt, slightly rolled.<\/p>\n

It can be confused with Aldisa banyulensis<\/em> Pruvot-Fol, 1951, that despite it\u00a0is also red with two dark spots on the back, it is smaller (with a maximum of 15 mm), has the white dorsal band located right\u00a0before the second dorsal spot, it has 8 completely translucent red (without white tips) gill leaves, rhinophores with more numerous lamellae that are horizontally arranged, the rhinophoric\u00a0sheaths\u00a0and gill sheath with smooth edges, with flattened and triangular, pointy, oral tentacles, it feeds on another sponge: Hemymicale columella,<\/em> and put less eggs that are larger (200\u03bcm in diameter). There is another species with which could be confused, Aldisa expleta<\/em> Ortea, Perez & Llera, 1982, but it lacks the dark dorsal spots.<\/p>\n

Biology
\n<\/strong>Lives on rocky bottoms, from 3 m depth, where it feeds sponge Phorbas fictitius<\/em> (Bowerbank, 1866) and is usually found on it, as it has the same coloration as the sponge and the dark spots on the dorsum\u00a0mimic the\u00a0inhalent openings, called pore-sieves (cribri), of the\u00a0sponge, in what is known as crypsis by homocromy. For this reason it is a difficult to see species, and is considered rare. The spawn\u00a0is a single turn of 1 cm diameter with capsules containing relatively small red eggs (130\u03bcm in diameter) each. Skin produces certain substances similar to\u00a0progesterone.<\/p>\n
