Turris Explained
Turris is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids.
Description
The generally large shells are variegated with spots. The fusiform shell is turriculated with a long, sharp spire. The aperture is ovate. The columellar lip is smooth. The outer lip is separated with a narrow profound sinus from the suture rather than distantly. The siphonal canal is long and narrow, straight and open.[1]
(Description by Charles Hedley) The shell is large, with a tall slender spire. The outer lip is sharp, without fold or thickening. The siphonal notch is a deep slit with parallel sides following a walled-in fasciole. Within the body whorl are sharp raised revolving threads, a feature shared by related genera. The protoconch consists of two smooth rounded whorls. The operculum is unguiculate, with an apical nucleus.[2]
The foot of the animal is anteriorly truncated but obtuse posteriorly. The tentacles are cylindrical, with the eyes externally near their base The teeth of the toxoglossan radula are falciform and angulated (formula 1-0-1).
Distribution
This genus inhabits warm seas.
