""'Haustellum wilsoni " "'is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.
While mandibles or'jaws'( chewing mouthparts ) are only present in the caterpillar stage, the mouthparts of most adult Lepidoptera mainly consist of the sucking kind; this part is known as the proboscis or'haustellum '.
Members of " Haustellum " generally differ from those of " Vokesimurex " in having a globose and low-spired shape, a more rounded columella, a less deep anal notch, and no cord spine.
