Description
This species can reach more than 40 mm in length. The body is white and slightly translucent, with the back tinted reddish or light pink, slightly darker between the first groups of cerata and with bluish tones in some areas. There are two long orange spots on the head. The oral palps are slightly bluish at the base and opaque and tinted orange in the tip. The rhinophores are smooth and translucent at the base and rounded with short orange warts near the tip, the apex itself is white. The cerata are grouped in 8-10 groups on each side of the body, arranged more or less evenly over the dorsum. The cerata are colored blue with an orange apical end, they are long, narrow and hold the brown digestive gland but it is masked by the blue coloration of the cerata skin. The foot is wide and coloured soft pink and the anterior zone holds and a pair of fine triangular propodials palps.
Biology
This species can be found under stones or in shallow infralittoral rocky walls with plenty of hydrarians and other invertebrates. It has been reported that it feeds on anemones Aiptasia mutabilis and Sagartia sp. The spawn consists of a white, translucent spirally wound ribbon of about 25mm in diameter with eggs 125 microns of diameter.
Etymology
- Berghia. In honor of the Danish physician and malacologist Dr. Rudolph Bergh, (1824-1909).
- Coerulescens. Colored blue.
Distribution
B.coerulescens is present along the Atlantic coasts of Europe and the western Mediterranean, including the Adriatic. In the Iberian Peninsula it has been found in the Cantabrian coast, the coast of Portugal, in the Straits of Gibraltar and in all the Mediterranean shores. In Catalonia it has been reported in various localities of the Costa Brava, such as Cadaqués, L’Escala, Palamós, Lloret and Tossa de Mar.
The presence of the genus Berghia Trinchese, 1877 in the western Atlantic has been the traditional object of discussion in malacological circles. The Atlantic species were assigned by the first authors to the European species Berghia coerulescens (Laurillard, 1830) and Berghia verrucicornis (A. Costa, 1864), which is why they were considered ampiathlantic species. However, several authors already suspected the existence of different Berghia species in the western Atlantic (Edmunds, 1968; García-Gómez & Thompson, 1990; Muniain & Ortea, 1999), however the lack of specimens from the western Atlantic for their study prevented clarifying the taxonomy of the genus until the work by Dominguez et al. (2008).
Similar species
Trinchesia caerulea, with the rhinophores smooth and thin, while B.coerulescens has them thick and with orange coloured warts.
