Identification Guide
Identifying the Purple Olive (Oliva violacea) requires attention to specific features. Key aspects include shell shape, color, and size, as well as comparisons to similar species. This guide provides detailed points to assist in recognizing this unique marine snail.
How to Identify a Purple Olive
To identify a Purple Olive, start with the shell. The shell is elongated and can reach up to
5-10 cm in length. It features a smooth texture with deep grooves. The color varies from lavender to purplish-brown, often with a glossy finish.
Look closely at the aperture, which is the opening of the shell. It is elongated and can appear slightly flattened. The interior of the shell is typically a pale color. Observing these characteristics will help confirm the identification of the Purple Olive.
Characteristics
Purple Olives display several distinct characteristics. Aside from their notable size, they have a unique
spindle-shaped form that tapers at both ends. The color patterns on the surface can vary, sometimes showing bands or spots that help in identification.
Their shells are also characterized by a sleek and shiny surface, making them visually appealing. The deep spiral grooves along the shell add to their unique texture. When spotted on beaches, they can sometimes be found along with hermit crabs in occupied shells.
Comparison To Similar Species
In comparison to similar species, the Purple Olive can be differentiated from the Atlantic Olive (Olivella spp.). The Atlantic Olive's shell is generally smaller and less elongated.
Another similar species is the California Olive (Oliva callosa), which has a more rounded shell and a duller color. While both share a similar habitat, the color and shape differences are clear. Noting these differences will help distinguish the Purple Olive from its relatives in various coastal environments.
