Doriopsilla pelseneeri is a species of sea slug, a nudibranch, in the family Dendrodorididae. These colorful invertebrates are commonly found in intertidal and subtidal zones, adding vibrancy to the diverse marine ecosystems they inhabit.
Description & Characteristics
Doriopsilla pelseneeri is a relatively small nudibranch, typically reaching a maximum size of around 20 mm in length. Its body is elongated and oval-shaped, adorned with a characteristic pattern of bright orange or red spots against a background of white or cream. This striking coloration serves as a warning to potential predators, indicating the slug’s unpalatability due to the presence of toxins it accumulates from its diet.
Habitat and Occurrence
Doriopsilla pelseneeri is predominantly found in intertidal and subtidal zones, along the coasts of the northeastern Atlantic Ocean. They are particularly prevalent in the British Isles, where they inhabit rocky shores and seagrass meadows. This species also occurs in the North Sea and the Mediterranean Sea, showcasing its adaptability to various marine environments.
Taxonomy
Doriopsilla pelseneeri belongs to the class Gastropoda, the largest and most diverse class of mollusks, encompassing a vast array of shell-bearing and shell-less creatures. Within this class, the species is classified under the order Nudibranchia, a group of predominantly shell-less marine gastropods known for their striking colors and patterns. The family Dendrodorididae, which Doriopsilla pelseneeri belongs to, includes a variety of colorful and often strikingly patterned nudibranchs, further highlighting the diversity of this fascinating group.
Feeding
Doriopsilla pelseneeri is a carnivorous nudibranch, feeding primarily on sponges. These sponges, often brightly colored and textured, provide the slug with a source of food and a means of incorporating toxins for defense. This dietary choice contributes to the nudibranch’s distinctive coloration and its ability to deter predators.
