Description
Inermicosta inermicosta is a species of predatory sea snail belonging to the family Muricidae. Its shell is characterized by a robust, turbinate to fusiform shape with a moderately elevated spire. The surface features prominent, rounded axial ribs and intersecting spiral cords, giving it a rough, sculptured appearance. Coloration typically ranges from off-white to grayish-brown, often adorned with darker brown or purplish-brown axial bands or blotches. The aperture is ovate, and the shell possesses a short, open siphonal canal. These snails are found in shallow marine waters of the Western Atlantic, where they prey on other mollusks and barnacles.
