Aphelodoris rossquicki is a species of sea slug, a nudibranch, a shell-less marine gastropod mollusk in the family Dorididae. It is a colorful and distinctive species, known for its unique characteristics and habitat preferences.
Description & Characteristics
Aphelodoris rossquicki is a relatively small nudibranch, typically reaching a maximum size of around 25 mm. Its body is typically a vibrant orange or reddish-orange color, often with patches of yellow or white. The mantle is covered with numerous, small, white tubercles, giving it a slightly bumpy appearance. The rhinophores (sensory organs) are elongated and club-shaped, while the gills are feathery and arranged in a cluster at the posterior end of the body.
Habitat and Occurrence
Aphelodoris rossquicki is typically found in shallow, rocky intertidal zones and subtidal habitats. It is a common species in the coastal waters of southern Australia. It is primarily found in the temperate waters of the Indo-Pacific region, particularly in the southern Australian states.
Taxonomy
Aphelodoris rossquicki belongs to the Class: Gastropoda, Order: Nudibranchia, and Family: Dorididae. This classification places it within the larger group of gastropod mollusks, specifically the order of nudibranchs, commonly known as sea slugs. Within the family Dorididae, it is part of a diverse group of nudibranchs characterized by their smooth, oval-shaped bodies and prominent gills.
Feeding
Aphelodoris rossquicki is a carnivorous nudibranch, primarily feeding on sponges. It uses its radula, a ribbon-like structure in its mouth, to scrape and ingest the sponge tissue. Its diet is thought to consist of various sponge species, including those found in its rocky intertidal and subtidal habitats.
