Phyllidia multituberculata is a species of sea slug, a nudibranch, belonging to the family Phyllidiidae. These colorful and fascinating creatures are known for their distinctive appearance and unique adaptations to their marine environments.
Description & Characteristics
Phyllidia multituberculata is a medium-sized nudibranch, typically reaching a maximum size of around 50 mm in length. Its body is characterized by a flattened, oval shape and a distinctive mantle, which is a fleshy, dorsal covering that extends beyond the body’s edges. The mantle is covered in numerous tubercles, giving the species its name “multituberculata.” The color of Phyllidia multituberculata varies, with individuals exhibiting a range of hues from dark gray to brown, often with contrasting white markings. The presence of these tubercles and the overall coloration help Phyllidia multituberculata to blend seamlessly with the rocky surfaces and coral reefs where they reside.
Habitat and Occurrence
Phyllidia multituberculata is a common inhabitant of tropical and subtropical coral reefs, specifically the Indo-Pacific region. Its typical depth range extends from the intertidal zone to depths of around 25 meters, making it a prevalent presence in these aquatic ecosystems.
Taxonomy
Phyllidia multituberculata belongs to the Class: Gastropoda, Order: Nudibranchia, and Family: Phyllidiidae. This classification places it within the larger group of mollusks, specifically within the suborder of marine gastropods known as Nudibranchia, which are characterized by their lack of an external shell. Within the Phyllidiidae family, Phyllidia multituberculata exhibits unique characteristics that distinguish it from other members of this diverse group.
Feeding
Phyllidia multituberculata is a carnivorous nudibranch, feeding primarily on sponges. It locates its prey using its highly developed sense of smell and then uses its radula, a ribbon-like structure in its mouth, to scrape the sponge’s tissue. Like many other nudibranchs, Phyllidia multituberculata can absorb and store the toxins from its prey. This unique ability provides a form of chemical defense against predators, making it a less desirable target for potential attackers.
