The False Doris, scientifically known as Adalaria proxima, is a species of sea slug belonging to the family Onchidorididae. These nudibranchs are characterized by their vibrant colors and unique body shapes, making them a captivating sight in the marine environment.
Description & Characteristics
Adalaria proxima is a relatively small nudibranch, typically reaching a maximum size of around 25 millimeters. Its body is elongated and oval-shaped, with a smooth and glistening surface. The dorsal side of the False Doris is usually adorned with a striking pattern of white or yellow spots on a background of red, orange, or brown. This color pattern provides excellent camouflage against the rocky and kelp-covered habitats they inhabit.
Habitat and Occurrence
Adalaria proxima exhibits a preference for cold-water environments, particularly those with a rocky substrate. They are frequently found in fjords, intertidal zones, and tidal zones. These nudibranchs are also commonly observed in kelp forests, where they seek refuge among the dense kelp fronds. The presence of Adalaria proxima in these diverse marine zones underscores its adaptability and ability to thrive in a range of habitats.
Taxonomy
The species Adalaria proxima belongs to the Class: Gastropoda, Order: Nudibranchia, and Family: Onchidorididae. These classifications reflect the evolutionary relationships and shared characteristics of this sea slug with other marine organisms.
Feeding
Adalaria proxima is a carnivorous and predatory nudibranch. Its diet primarily consists of bryozoans, also known as sea mats. These colonial animals provide a rich source of nutrition for the False Doris. The nudibranch uses its radula, a ribbon-like structure with rows of teeth, to scrape the bryozoans from their substrate and consume them.
