Description & Characteristics
Ranularia gutturnia, also known as the Long-neck Triton or Orange-mouthed Triton, is a large, robust snail. This species is easily identified by its elongated, somewhat cylindrical shell, which can grow up to 150 mm in length. The shell’s aperture, or opening, is large and oval-shaped, with a noticeable orange hue around the lip. The shell surface displays a series of prominent, rounded nodules, particularly near the shoulder, giving it a textured appearance. The overall coloration of the shell can vary, ranging from shades of brown and gray to creamy white, often with patches of brown or orange.
Habitat and Occurrence
The Long-neck Triton, Orange-mouthed Triton – Ranularia gutturnia is a species that thrives in the intertidal and subtidal zones. Typically inhabiting rocky reefs and seagrass beds, this snail prefers environments with a moderate to strong current. Its distribution encompasses a wide range, including the Indo-Pacific region. This species is commonly found in the following marine zones: the neritic zone, which extends from the shoreline to the edge of the continental shelf, and the epipelagic zone, the uppermost layer of the open ocean.
Taxonomy
The species Ranularia gutturnia belongs to the Class: Gastropoda, Order: Littorinimorpha, and Family: Cymatiidae. Gastropods, more commonly known as snails and slugs, are the largest and most diverse class of molluscs, characterized by their single, spiraled shell. The Littorinimorpha order contains a diverse range of marine snails, including many familiar species like periwinkles and moon snails. The Cymatiidae family, commonly known as tritons, encompasses a group of large, predatory sea snails known for their distinct, often bulbous shells.
Feeding
Ranularia gutturnia is a carnivorous and predatory snail. Its diet primarily consists of sea urchins and other snails, which it targets and consumes. This feeding strategy plays a crucial role in maintaining the balance of the marine ecosystem. The Long-neck Triton, Orange-mouthed Triton – Ranularia gutturnia uses its strong, muscular foot to pry open the shells of its prey, utilizing its radula, a ribbon-like structure covered in rows of teeth, to scrape and consume the soft tissues inside.
