A recently released video captures the unusual hunting behavior of Melibe viridis, a predatory sea slug found in Indonesian waters. The footage, filmed near Bali, showcases the animal’s unique method of capturing prey using a large, expandable oral hood.
A Unique Predator
Melibe viridis is a type of nudibranch, a shell-less marine gastropod. This species is distinguished by its soft body and the dramatic opening and closing movement of its oral hood, which it uses to trap small crustaceans and other tiny animals. The slug spreads this hood outward as it moves along the ocean floor, and rapidly closes it when prey makes contact.
The frilly appendages along the body of Melibe viridis are not legs, but part of its soft body structure, aiding in movement and hunting. The animal typically crawls along the seafloor, but can move in other ways when disturbed.
Understanding Nudibranchs
Even as often called sea slugs, not all sea slugs are nudibranchs. However, Melibe viridis is both – a sea slug and a nudibranch. These creatures are known for their unusual shapes and feeding styles, attracting the attention of divers and marine-life enthusiasts.
The footage of Melibe viridis was filmed by Emeric Benhalassa and shared by Ocean Vizion.
