Shell description
The shells grow from 8 to 13 centimetres (3 to 5 in) long.[6] The shell is light brown in color and is covered with gray-brown bristly periostracum, hence the name "hairy." The shell is an elongate cone with six whorls (or turns) around a central axis.

This species is common
Life habits
Little is known of the snail's feeding habits, but they are believed to feed on other mollusks,[6] ascidians ("sea squirts"),[8] and more rarely, sea urchins.[9] The species also holds the record for longest larval development period of any marine invertebrate, able to delay metamorphosis for over 4 years until presented with appropriate habitat.[10] Under laboratory conditions, the larvae showed no signs of senescence at that point. According to some authorities, four years is long enough to drift completely across the Pacific Ocean.
