Oxymeris crenulata, commonly known as the “Crenellated Auger,” is a species of sea snail that belongs to the family Terebridae. These gastropods are characterized by their elongated, slender shells, often with intricate patterns and textures. Oxymeris crenulata is renowned for its unique morphology and distinct habitat preferences.
Description and Characteristics
Oxymeris crenulata is a medium-sized gastropod, reaching a maximum length of approximately 50 millimeters. The shell of Oxymeris crenulata is typically cream-colored, often with reddish-brown or orange markings. The shell is elongated and pointed, with a smooth, glossy surface. A prominent feature of Oxymeris crenulata is the series of crenulated (scalloped) ridges that run along the whorls of the shell. The aperture of the shell is narrow and elongated, with a distinct siphonal canal. These distinctive features contribute to the unique appearance of Oxymeris crenulata, helping to differentiate it from other species within the Terebridae family.
Habitat and Occurrence
Oxymeris crenulata is found primarily in shallow, tropical waters of the Indo-Pacific region. It is frequently observed in intertidal zones, particularly on sandy or muddy substrates. The species exhibits a strong preference for environments with abundant seaweed and algal growth, providing a source of food and shelter. These habitats are often located in the neritic zone, which encompasses the coastal waters extending from the shoreline to the edge of the continental shelf. The distribution of Oxymeris crenulata extends across various marine zones, including the tropical Indo-Pacific. Its presence in these habitats underscores its ecological importance and adaptability within a diverse range of marine ecosystems.
Taxonomy
Oxymeris crenulata belongs to the Class: Gastropoda, Order: Neogastropoda, and Family: Terebridae. This classification places Oxymeris crenulata within a large and diverse group of marine snails known for their elongated, pointed shells. The Terebridae family encompasses a wide range of species, each with unique adaptations and ecological roles within their respective habitats.
Feeding
Oxymeris crenulata is a carnivorous gastropod. It feeds primarily on polychaete worms and other small invertebrates found within its sandy or muddy habitat. Oxymeris crenulata uses its radula, a ribbon-like structure covered in teeth, to scrape and tear its prey. The feeding habits of Oxymeris crenulata contribute to the balance of the marine ecosystem by controlling populations of benthic invertebrates.
