Body elongated, relatively high in the middle, with a narrow overhang of the mantle edges along the sides, widening anteriorly. Rhinophores lamellated and retractile. Gils forming a circle of 10-12 plumes posteriorly around the anus.
color pattern rather complex and variable that results from a combination of different proportions of the basic colors. Background body color cream or greenish. Edge of the notum pale blue with a line of darker blue and yellow spots. Surface of notum sprinkled with small yellow dots, dark spots and an irregular and variable pattern of white pigmentation along the axis. Rhinophores bright orange-red with a white stalk. Gill plumes white each with a reddish rachis.
common size :
30-40 mm, max. 55 mm.
Hypselodoris infucata belongs to a complex of very closely related species in the Indo-Pacific region (Rudman, 1973, 1977), under revision by Johnson and Valdés (2001). Sometimes it has been confused with H. obscura (Stimpson, 1855). All Mediterranean species of the genus Hypselodoris have a pattern of yellow or white longitudinal bands over a dark blue background color. Hypselodoris infucata clearly differs from them by the red pigmentation of rhinophores and branchial plume and by its color pattern of yellow and blue spots over a cream or greenish background.
BIOLOGY / ECOLOGY
The reproduction and larval development have been studied by Hubbard (1988). Adults lay spiralled, whitish, ribbon-like egg masses. The veliger larvae hatch after about five days at 25°C and can lead a planktonic life for about three weeks.
on rocky bottoms of the infralittoral zone. Species very tolerant to harbour conditions.
