Trapania naeva is a species of sea slug, a nudibranch, a marine gastropod mollusc in the family Goniodorididae. Trapania naeva, commonly known as the “Trapania naeva”, is a relatively small nudibranch, reaching a maximum size of around 15 millimeters in length.
Description & Characteristics
Trapania naeva is a strikingly colorful nudibranch with a translucent white body and bright orange or yellow rhinophores (sensory organs) and cerata (protrusions along the back). The cerata are often tipped with a bright blue or green pigment, adding to the slug’s vivid appearance.
Habitat and Occurrence
Trapania naeva is found in the tropical waters of the Indo-Pacific region, typically inhabiting shallow reefs and sandy bottoms. It is most commonly observed in the intertidal zone and the subtidal zone down to a depth of around 20 meters. Trapania naeva is a relatively common species in its habitat, particularly in areas with abundant populations of its preferred prey.
Taxonomy
Trapania naeva is classified within the Class Gastropoda, Order Nudibranchia, and Family Goniodorididae. This family encompasses a diverse range of nudibranchs characterized by their distinctive external features and feeding habits.
Feeding
Trapania naeva is a specialist feeder, specializing in consuming a specific type of marine worm known as Kelchwürmer (Entroprocta). These worms are sessile, meaning they are attached to a surface and unable to move freely. Trapania naeva uses its radula, a toothed ribbon in its mouth, to scrape the worms off surfaces and consume them.
