Rapana( Rapana thomasiana, Rapana pontica,Rapana bezoar, Rapana venosa), is a marine snail which belongs to the Muriciade family, the  Gastropod class, the Mollusk branch. It lives in the sandy and rocky substratums  which are offshore from the coastal line until 30 metres depth.

Mentioned for the first time in the Black Sea in 1948 in the neigbourhood of  Novorossiik port, Russia, it starts to make its appearance in 1963 on the Romanian coast. Rapana has its origin in the Japan Sea, the China Sea and the Yellow Sea where it was accidentally brought being carried  on the bottom hull of the ship.

RAPANA  is a gastropod  which has a big size, with a globular and thick shell, with a spiral shell  made of  7-8 whorls separated by deep sutures. The upper part of each whorl  is covered with horn-like tubercles. It can reach a length of 190 mm and the width of 160mm.The siphonal canal is relatively short and large, with a deep cut. The surface is differently  ornamented and it presents a row of nipples ranged in a spiral line. One can also notice on its shell longitudinal grooved ribs. The opening is very large, with an oval shape, shiny on the inside having a reddish-orange colour.  The colour of the shell ranges from pale yellow  to brownish-reddish usually with brown stripes  or more intensly  coloured  lines. The interior of  the opening is bright orange, yellow or brown.

RAPANA multiplies by eggs. The duration of the incubation is of approximately  17 days,  weather conditions permitting  ( 18-20 degrees Celcius). The  life period  of the species is of 10 years, and in 2 years a young rapana reaches the dimensions of an adult.
