Species Profile
The dubbelvinge (Pleurobranchus membranaceus) is a large sea slug belonging to the nudibranch family, characterized by its distinctive translucent, membranous body with prominent wing-like extensions called parapodia. This marine gastropod can reach lengths of up to 12 centimeters and displays a pale, gelatinous appearance with visible internal structures. As a carnivorous predator, it plays an important role in marine ecosystems by feeding on sponges, tunicates, and other soft-bodied invertebrates.
Pleurobranchus membranaceus faces increasing pressure from coastal development and marine pollution, which degrade the shallow marine habitats essential for this sea slug's survival. Ocean acidification and rising sea temperatures associated with climate change further threaten the species by affecting both the mollusk itself and its prey organisms.
