Nassarius vibex, commonly known as the Common Eastern Nassa, can be found from Cape Cod to Florida, the Gulf States, and the West Indies. This Nassarius species can also be found in Brazil. Even though the Common Eastern Nassa is widely dispersed, it spends most of its time either in Florida or in the Caribbean. (Warmke and Abbott 1962; "Livestock" 4/28/01; "Nassariidae" 4/10/01; "Nassarius vibex" 4/19/01; "An Alternative to Hermit Crabs!" 4/19/01)

The Common Eastern Nassa can be anywhere from 10mm to 1 cm long, when the Nassa is an adult. The shell that is its home has a pointed "cone-shaped" spiral. The shell can be white to yellow to light or dark brown. Usually, there are either ridges or bumps on the shell as well. The shells are distinguished by a groove in the front, lower part of the shell. There can be varied colorations of the shell. Some people may think that two Common Eastern Nassas are actuallly different species because of the different colorations, when in fact, it is the same species. Some dark color bands may also be visible on the shells. Scientists believe that Nassarius vibex has twelve longitudinal ribs that are crossed with finer revolving threads. Also, this Nassa has the ability to extend its mouth so it is almost as long as the length of its body. When this occurs, it looks like an elephant's trunk. From research, scientists have determined that Nassarius vibex can live for several years. (Warmke and Abbott 1962; "Livestock" 4/28/01; Mann, Roger and Juliana Harding April 17, 2001; "Nassarius vibex" 4/19/01; "Nassariidae" April 10, 2001; "An Alternative to Hermit Crabs!" 4/19/01)

Nassarius vibex is most commonly found living in the intertidal sand flats or in mud flats. This species can also be found living in very shallow waters and in creek banks. Most of the time, Nassarius vibex is buried under the sand or the mud. Because of where the Common Eastern Nassa lives, it lives at normal reef temperatures and conditions.

The diet of the Common Eastern Nassa consists mainly of carrion and some eggs of certain sand-dwelling polychaetes. The Nassa comes out of the sand to eat the carrion and, most of the time, it must move up-current to eat. Scientists and researchers are not sure if they are obligate carrion-feeders. Obligate carrion-feeders are those animals that will not harm most or all other animals in the systen in which they are living. ("Livestock" 4/28/01; "An Alternative to Hermit Crabs!" 4/19/01)
