Description

The length of the shell varies between 75 mm and 122 mm. The shell is fusiform, with a pointed apex and a smooth, glossy surface. The coloration is typically a light brown or beige, often with darker spiral bands.^[2]

It is found in deep-sea environments, typically at depths ranging from 200 to 1000 meters. It inhabits sandy or muddy substrates where it preys on smaller invertebrates. This species is adapted to cold, high-pressure environments of the deep sea and plays a role in the benthic ecosystem as a predator.
