Classification provided by the World Register of Marine Species (WoRMS). [141405<\/a>]<\/p><\/div>Description<\/strong>
\nThese animals use to be between 1.5 and 2.5 mm in length. The body is dark brown and it is almost entirely covered by black spots on the dorsum and on the foot. There are also numerous whitish or cream colored dots which can concentrate to form spots or bands, among which stands out a transverse band, sometimes incomplete, on the first third of the body and a more diffuse longitudinal line extending from the head to the posterior area of the notum, where it connects with a thicker white band located at the border of the notum. The cephalic region lateral zones are colored with light tones are also whitish dotted. The eyes are visible in these clear cephalic areas. In some specimens the black spots on the back concentrate forming other black bands right behind the white transversal anterior band and ahead of the rear area of \u200b\u200bthe back. In the foot there are also black spots forming a central dark band that can be seen in the tail. The notum is raised in the back forming a paleal ridge, where there are two small semitransparent gills.<\/p>\n

Biology<\/strong>
\nIn the Mediterranean it seems to be a very common species living among Posidonia oceanica<\/em> rhizomes, something confirmed in recent studies. It is a herbivorous species that due to its small size and crypsis on the Posidonia<\/em> rhizomes, it is very difficult to observe in nature.<\/p>\n
