Pellasimnia angasi is a species of small, colorful sea snail, a marine gastropod mollusk in the family Ovulidae, commonly known as the cowry snails. This species is particularly notable for its vibrant and intricate shell patterns, which often feature a blend of orange, brown, and white hues.
Description & Characteristics
Pellasimnia angasi is a relatively small species, with adult individuals typically reaching a maximum size of around 15 millimeters. The shell of Pellasimnia angasi is characterized by its smooth, glossy surface and ovoid shape. The aperture, or opening of the shell, is located at the ventral side and is typically narrow and elongated. The outer lip of the aperture is often thickened and slightly flared, while the inner lip is smooth and glossy.
The most striking feature of Pellasimnia angasi is its colorful and intricate shell patterns. The base color of the shell is typically a creamy white or pale orange. These patterns often feature a combination of brown, orange, and white blotches, streaks, and spots, creating a unique and visually appealing appearance.
Habitat and Occurrence
Pellasimnia angasi is a predominantly tropical species, found in the Indo-Pacific region. This species typically inhabits shallow water environments, primarily in coral reefs and rocky shores. It is known to occur in depths ranging from the intertidal zone to about 20 meters. The Pellasimnia angasi is often found in association with its preferred prey, which are other marine snails.
Taxonomy
Pellasimnia angasi is classified within the Class Gastropoda, Order Littorinimorpha, and Family Ovulidae. This family encompasses a diverse range of marine snail species, many of which are characterized by their smooth, ovoid shells and vibrant colors. The species is classified within this group due to its shared anatomical features and evolutionary relationships.
Feeding
Pellasimnia angasi is a carnivorous species, feeding primarily on other marine snails. The Pellasimnia angasi uses a specialized radula, a chitinous ribbon covered in teeth, to scrape and ingest the flesh of its prey. This feeding behavior is typical of many cowry snail species, highlighting their predatory nature within the marine ecosystem.
