The Acanthodoris mollicella, commonly known as the Nudibranch, is a captivating and fascinating sea slug belonging to the family Onchidorididae. This species is recognized for its vibrant colors and intricate patterns, showcasing the beauty and diversity of the marine world.
Description & Characteristics
The Acanthodoris mollicella is a small to medium-sized nudibranch, typically reaching a maximum size of 40 mm in length. Its body is characterized by a soft, almost gelatinous texture. The dorsal surface, or back, is often adorned with a stunning array of colors, including shades of orange, red, and yellow, interspersed with intricate black markings. These vibrant hues and patterns provide a remarkable camouflage, helping the Acanthodoris mollicella blend seamlessly with its surroundings.
Habitat and Occurrence
The Acanthodoris mollicella is a common inhabitant of various marine zones, ranging from the subtidal to the deeper regions of the oceans. It is frequently found in the sublittoral, infralittoral, and deep zones, encompassing the lower limit of the intertidal zone and extending down to the shelf edge at approximately 200 meters water depth. This wide distribution reflects the species’ adaptability and resilience in a variety of marine environments. Its neritic habitat further emphasizes its presence in coastal waters.
Taxonomy
The Acanthodoris mollicella belongs to the Class: Gastropoda, Order: Nudibranchia, and Family: Onchidorididae. This classification places it within the broader group of mollusks known as gastropods, which encompasses a diverse range of species including snails, slugs, and sea slugs. The Nudibranchia order, to which the Acanthodoris mollicella belongs, is comprised of a highly diverse and visually stunning group of sea slugs.
Feeding
The Acanthodoris mollicella is known to be a specialist feeder, primarily consuming bryozoans, commonly referred to as sea mats. These colonial organisms provide a crucial food source for the Acanthodoris mollicella, allowing it to thrive in its chosen habitat. While this information is generally accepted, further research may reveal other dietary components or preferences for this fascinating species.
