This species can reach a size of up to 60 mm in length. Although variable in coloration, most specimens are dark brown with numerous tiny rounded white spots or larger and irregular shaped spots, their density changing from an specimen to another. However in some animals the color is almost black or reddish brown with little white scores. The head shield is well developed and occupies the anterior half of the body, its anterior border is decorated by an orange band and can also show two longitudinal stripes of the same color, that can be discontinuous. The mantle ends in two rounded lobes without flagellum. The parapodia are relatively short and left uncovered much of the head shield and mantle. The white spots are also present on the outer face of the parapodia. The trailing edge of the head shield, the posterior parapodia and mantle lobes are fringed with a thin line of blue pigment and a wider band of orange. The foot is dark brown, almost black, and has a faint bluish iridescence giving it a velvety appearance, in the anterior zone it widens a little, forming the two rounded lobes.
P. depicta lives on soft sand bottoms, or sand and mud bottoms where it can burrow itself to search for food. When animals are roaming on the substrate they usually lift the back of the head shield. This species is a voracious predator of invertebrates and even other species of opisthobranchs, which captures by projecting its bucal bulb outwards and swallowing the prey whole. It has been cited that feeds among other cephalaspidean species of Bulla striata and Haminoea sp. and some of the smaller species of Aglaja.
- Philinopsis. From Latin, means “similar to Philine“, where Philine is another genus of Cephalaspideans.
- Philine. Derived from Greek “philainoi”, name of two Carthaginian brothers who fougth for their homeland and who received honors as Gods.
- Depicta, derived from Latin word “picta”, for painted.
It is essentially a Mediterranean species, having been cited in both the eastern and western basin. Outside the Mediterranean it has been observed in the Bahamas and the Canary Islands. In the Iberian Peninsula it is cited in Portugal, the Atlantic and Mediterranean coasts of Andalusia and the Eastern coast of Valencia. In Catalonia it is found in the sandy Ebro delta and on trawling grounds in front of Blanes.
