The European Sting Winkle, Oyster Drill, scientifically known as Ocenebra erinaceus, is a predatory marine snail belonging to the family Muricidae. It is a common and conspicuous species found in various coastal areas of Europe.
Description & Characteristics
The European Sting Winkle, Oyster Drill, Ocenebra erinaceus, is a medium-sized marine snail, reaching a maximum length of around 5 centimeters. Its shell is typically a reddish-brown color with a rough, spiky exterior, a feature that contributes to its common name. This rough texture is due to numerous small, pointed projections, or “spikes,” along the whorls of the shell. The aperture, or opening of the shell, is oval and is usually a lighter shade of brown than the rest of the shell.
Habitat and Occurrence
The European Sting Winkle, Oyster Drill, Ocenebra erinaceus, prefers rocky shores and intertidal areas, where it can be found clinging to rocks, seaweed, and other hard surfaces. It is commonly found in the lower intertidal zone and the shallow subtidal zone, typically residing in depths ranging from the low tide mark to a maximum of 50 meters. This species is a common inhabitant of the neritic zone, the marine environment extending from the shoreline to the edge of the continental shelf. Its geographic distribution includes the coastal regions of the North Sea, the Baltic Sea, the Mediterranean Sea, and the Atlantic coast of Europe.
Taxonomy
The European Sting Winkle, Oyster Drill, Ocenebra erinaceus, is classified within the phylum Mollusca, belonging to the Class Gastropoda, Order Neogastropoda, and Family Muricidae. The family Muricidae comprises a diverse group of predatory sea snails known as murex snails, many of which have shells with characteristically spiky or knobby structures.
Feeding
The European Sting Winkle, Oyster Drill, Ocenebra erinaceus, is a predatory snail that feeds primarily on bivalve mollusks, such as clams, mussels, and oysters. It uses its radula, a rasping tongue-like structure, to drill holes into the shells of its prey. Once a hole is made, the snail inserts its proboscis, a long, tubular structure, into the hole and consumes the soft tissues of the prey. This feeding strategy has earned it the common name “Oyster Drill” as it is known to prey on oysters, a valuable commercial species.
