Ranularia caudata, the bent-neck triton, is a species of predatory sea snail, a marine gastropod mollusk in the family Cymatiidae.
Description (Described in Latin as Triton canaliferum Lamarck, 1822) The shell is somewhat pear-shaped and features a distinct siphonal canal at the base. The surface is sculpted with transverse furrows and longitudinal, fold-like nodules, which create a slightly decussated (criss-crossed) texture. Its coloration is a tawny-white.
The whorls are channeled at the sutures, and the spire is notably short. The most striking feature is the siphonal canal, which is remarkably slender and graceful.
The size of a shell of an adult snail varies between 38 mm and 94 mm.
Distribution
This species occurs in the Indo-West Pacific along Tanzania.
