Trapania maculata (Haefelfinger, 1960)
Trapania maculata Haefelfinger, 1960
|Classification according to Bouchet et al. (2017)|
Taxonomic source: World Register of Marine Species (AphiaID: 140044).
This species can reach 15-20 mm in length. The body is whitish, almost transparent in the areas with no viscera, but it is clearly identified by the yellow or orange spots spots on the dorsal part of the head, oral and buccal palps, rhinophores, dorsum, body side walls, gill leaves and tail. The shape and arrangement of these spots varies among specimens. There are two pairs of tentaculiform pallial bumps of the same colour raising from the base of each rhinophore and the base of the gills. The rhinophores are whitish or semitransparent in the base, but the lamellae and apex are yellow. Three gill tripinnate leaves surround the anal papilla. The gill leaves have the central shaft and the lamellae coloured yellow while the rest is semi-transparent white. The tail has a fairly constant elongated yellow stain on its dorsal area.
This species of nudibranch can be found in dark rock walls, wandering or on different species of sponges. It seems that it feed on the endoprocta living on sponges rather than feeding on sponges. Spawn of Trapania maculata is formed by a transparent gelatinous ribbon 3-4 mm high, irregularly coiled, with irregularly placed white eggs: on top of the ribbon there are 10 to 15 eggs in two layers but only 4-5 eggs at the end of the ribbon, where it is narrower.
- Trapania. Bernard Picton considers this derives from Greek Drepane meaning “sickle” or “reaping hook”, presumably referred to the appendixes located in the base of rhinophores and gills in the genus Trapania.
- Maculata, from Latin maculatus, meaning “stained”.
This is a species that has been cited throughout the European coasts, both Atlantic and Mediterranean, and all around the Iberian Peninsula coasts. In Catalonia it is a common species throughout the rocky coastline.
