Aristofusus excavatus, common name apricot spindle, is a species of sea snail, a marine gastropod mollusk in the family Fasciolariidae, the spindle snails, the tulip snails and their allies.[1]
Description
Aristofusus excavatus has a shell reaching a size of 60 – 86 mm. The surface of this spindle-shaped shell is yellowish, with darker yellowish areas.
(Original description in Latin) The shell is slender and fusiform, with a tawny (fulvous) base color.
It is characterized by prominent spiral lirae (ridges) with finer interstriae (fine grooves between the ridges). The shell is also adorned with prominent, widely spaced axial ribs (costae). These ribs are tuberculate-lirate (ridged and bearing distinct nodules/tubercles).
The shell comprises 10 prominent whorls. These whorls are distinctly and deeply excavated or channeled just below the suture.[2]
Distribution
This species can be found in southeastern United States and from the Gulf of Mexico to northeastern Brazil. It lives on sandy and mud bottoms at depths from 30 to 160 m.
