External morphology

Body elongate, thick, background colour light green with small brown and white dots along body, and a white pigmented area between eyes. Cerata numerous, flat; transparent with green lines running towards apex. Rhinophores long, folded, divided in ‘Y’ shape, tips divided into two unequal parts.

Ecology

Specimens found at night and during the day on the green algae Bryopsis duplex (De Notaris, 1844) and Cladophora prolifera laying egg masses. At night slugs actively crawled and laid egg masses, while by day they hid among the algae.

Distribution

Gulf of Mexico (BioGoMx 2021); Brazil (GBIF.org 2021); Gibraltar ( García-Gómez 2002); Atlantic Spanish coast: Canary Islands ( Ortea and Bacallado 1981; Ortea et al. 1999, 2001; Moro et al. 2003); Mediterranean Spanish coast, Andalucía ( Luque 1983; García Raso et al. 1992; Ocaña et al. 2000), Levantine coast ( Templado et al. 1987, 2002), Balearic Islands (GROC 2009–2021), Catalonia (this study).

Remarks

This species is distinguished from similar ones like C. viridis ( Deshayes, 1857) (formerly Polybranchia viridis ) by the presence of a ramified digestive gland in the cerata (see Poybranchia viridis in Rudman 2021).

Genus Cyerce Bergh, 1870
