The Ceylon Gymnodoris, scientifically known as Gymnodoris ceylonica, is a captivating species of sea slug belonging to the family Polyceridae. These nudibranchs are fascinating creatures that exhibit striking coloration and intricate patterns, adding to the beauty of the marine environment they inhabit.
Description & Characteristics
Gymnodoris ceylonica is a relatively large nudibranch, reaching a maximum size of several centimeters in length. Its body is typically a vibrant blend of colors, often displaying a mix of red, orange, and yellow hues. The surface of its body is often covered in bumps or ridges, giving it a textured appearance. It also has a prominent oral veil, a flap-like structure surrounding its mouth, which it uses to capture prey.
Habitat and Occurrence
Gymnodoris ceylonica is a marine species that can be found in a variety of subtidal habitats, from the lower limit of the intertidal zone to the shelf edge at about 200 meters water depth. This means it inhabits the sublittoral, infralittoral, and deep zones of the oceans, classified as neritic. These nudibranchs are often found on rocky reefs and sandy bottoms, where they can find ample food and shelter. Their distribution spans a range of marine ecosystems, making them a common sight in these environments.
Taxonomy
Gymnodoris ceylonica belongs to the Class: Gastropoda, Order: Nudibranchia, and Family: Polyceridae. This classification places it within the broader group of mollusks, specifically the subgroup of sea slugs known as nudibranchs. The family Polyceridae encompasses a diverse array of nudibranchs, known for their often brightly colored bodies and distinct external features.
Feeding
Gymnodoris ceylonica is a predatory nudibranch, primarily feeding on snails. This dietary preference highlights its role as a predator in the marine ecosystem, helping to control populations of snails within its habitat.
