Cratena pilata is a species of colorful sea slug, a nudibranch, belonging to the family Facelinidae. It is known for its vibrant coloration and distinctive appearance.
Description & Characteristics
Cratena pilata is a small nudibranch, typically reaching a maximum size of 10 mm in length. It exhibits a slender, elongated body with a pointed head and a tail that tapers to a point. The body is covered in numerous cerata, finger-like projections that extend from the dorsal surface. These cerata are typically bright orange or yellow in color, with white or cream-colored tips. The rhinophores, the sensory organs located on the head, are also brightly colored, often featuring white or yellow tips.
Habitat and Occurrence
Cratena pilata is a widespread species, found in various regions of the world. It prefers to inhabit shallow coastal waters, particularly in the intertidal zone and subtidal regions. This species is commonly observed in rocky reefs, seagrass meadows, and kelp forests. Cratena pilata is known to be a resident of the neritic zone, the marine environment extending from the coastline to the edge of the continental shelf.
Taxonomy
Cratena pilata belongs to the Class Gastropoda, Order Nudibranchia, and Family Facelinidae. This classification places it within a diverse group of marine invertebrates characterized by their lack of shells and their distinctive external gills.
Feeding
Cratena pilata is a carnivorous species, feeding primarily on hydroids. These are colonial animals that are commonly found attached to rocks, seaweeds, and other surfaces. The nudibranch uses its radula, a chitinous structure in its mouth, to scrape the hydroids and consume their polyps.
