The animal on the cover of IPv6 Essentials is a rigatella snail. The rigatella snail, or Eobania vermiculata, is native to the Mediterranean region, especially to Turkey and Crete. The snail lives in gardens, hedges, and dunes, where it feeds on vegetation. The snail got its scientific name because the rings on its shell resemble vermicelli (a type of pasta). It is also sometimes called the "noodle snail."
