Decoradrillia halidorema ( synonym : Fenimorea halidorema ) is a sea snail from the family of Drilliidae thatlivesin the western Atlantic Ocean andeats polychaetes .

description

The height of the shell of the adult snail is between 14 and 25 millimeters. It has nine turns. Its color is pale pink. Striking is a chestnut brown band that runs along the lower part of the turns and is weaker or completely interrupted on the tubercles. In some specimens, a weaker colored geranium-colored pink runs beneath the maroon-brown band, which merges into white at the base.

The sculpture shows fairly broad axial ribs, which, in contrast to the very similar Fenimorea janetae, are smooth and without fine transverse lines. On the last turn, the chestnut brown ribbon runs centrally and uninterrupted over all ten ribs. The protoconch is paucispiral with one and a half whorls, smooth and white.

Occurrence

This species occurs in the shallow water zones of the western Atlantic , from northern Brazil over the Caribbean Sea , e.g. B. off Jamaica and off the coast of Colombia and in the Gulf of Mexico to the coast of Florida .

nutrition

As is with other original conoidea even with Decoradrillia halidorema the loot from Vielborstern (Polychaeta) that using the Radulazähne be caught by lethal injection. The snail is in strong interspecific food competition with other predatory snail species, especially the conoid.

Systematics and taxonomy

The snail was originally described by Reeve in 1845 as Pleurotoma pulchella . In 2016, Fallon placed it in the genus Decoradrillia , which he had newly established .
