The Orange-peel Doris, also known as the Orange-peel Sea Slug, is a vibrant and fascinating marine gastropod belonging to the species Acanthodoris lutea. This sea slug, characterized by its distinctive orange hue and textured surface, is a captivating sight in the underwater world.
Description & Characteristics
The Orange-peel Doris, Acanthodoris lutea, is a medium-sized sea slug, typically reaching a maximum size of about 30 mm in length. Its body is a striking orange color, often with a slightly reddish tint, and is covered in small, raised bumps that give it a distinctive, almost orange-peel-like texture. This textured surface, along with the slug’s bright coloration, serves as camouflage, helping it blend in with the surrounding environment.
Habitat and Occurrence
The Orange-peel Doris, Acanthodoris lutea, prefers temperate waters and is commonly found in the Northeast Atlantic, including the British Isles and the coasts of France and Spain. This sea slug is typically found in shallow, intertidal areas, often clinging to rocks and seaweed in the lower littoral zone. It can also be found in subtidal areas, with a depth range extending up to 50 meters. Its presence in these various marine zones highlights its adaptability and resilience in different underwater environments.
Taxonomy
The Orange-peel Doris, Acanthodoris lutea, is classified within the phylum Mollusca, belonging to the Class: Gastropoda, Order: Nudibranchia, and Family: Onchidorididae. This classification underscores its unique evolutionary lineage and its place among the fascinating and diverse group of sea slugs.
Feeding
The Orange-peel Doris, Acanthodoris lutea, is a specialist feeder, meaning it has a specific diet that it relies on. This sea slug feeds primarily on bryozoans, which are small, colonial animals often referred to as “sea mats.” The Acanthodoris lutea uses its radula, a ribbon-like structure with teeth, to scrape and ingest the bryozoans. This feeding behavior is crucial to the sea slug’s survival and contributes to the balance of the marine ecosystem.
