The Punctate Chelidonura , Headshield Slug, scientifically known as Chelidonura punctata, is a captivating species of sea slug belonging to the family Aglajidae. This species exhibits a remarkable array of characteristics that make it a fascinating subject of study for marine biologists and enthusiasts alike.
Description & Characteristics
Chelidonura punctata is characterized by its distinct, patterned body. It possesses a flattened, oval-shaped body with a prominent head shield. The surface of the slug is adorned with numerous, small, scattered white spots, which give it its characteristic punctate appearance. The color of the slug can vary, ranging from pale yellow to orange and even brown. The maximum size of this species is typically around 20mm.
Habitat and Occurrence
The Punctate Chelidonura , Headshield Slug is predominantly found in the Indo-Pacific region, inhabiting the tropical and subtropical waters of the area. It exhibits a preference for muddy grounds, particularly in shallow water environments. This species can be found at depths ranging from the intertidal zone to around 10 meters below the surface. This depth range places Chelidonura punctata within the Neritic zone, the marine environment that extends from the coastline to the edge of the continental shelf.
Taxonomy
The species Chelidonura punctata belongs to the Class: Gastropoda, Order: Cephalaspidea, and Family: Aglajidae. The Gastropoda class encompasses a wide variety of mollusks, including snails, slugs, and limpets. Within this class, the Order Cephalaspidea is characterized by its members’ flattened bodies and head shields. The family Aglajidae, to which Chelidonura punctata belongs, is comprised of several genera of sea slugs that share specific anatomical features, including their respiratory system.
Feeding
The Punctate Chelidonura , Headshield Slug is a carnivorous predator, specializing in feeding on turbellaria, commonly known as “Planaria.” These flatworms are frequently found in various marine environments, providing a readily available food source for Chelidonura punctata. The slug uses its specialized radula, a ribbon-like structure with rows of teeth, to capture and consume its prey.
