Adaptation and Form

C. gibbosum is about 1” long and has a peach colored shell with a lateral cream colored stripe that runs the length of the shell (PURA VIDA Divers 2012).  The shell appears to have yellow spots outlined in black but contrary to many beliefs the spots are not actually on the shell, they are a part of the snail’s mantle (PURA VIDA Divers 2012).  The flamingo tongue snail has mantle flaps that protrude and cover the shell (Marine Invertebrates of Bermuda 2007).  When under stress or it feels the threat of an attack, the snail retracts its mantle leaving the peach colored shell exposed (Encyclopedia Britannica 2013).  The mantle also acts as a set of gills that allow the snail to take in oxygen and expel carbon dioxide (Marine Invertebrates of Bermuda 2007).  The snails foot is its form of  locomotion.  Like most prosobranchs it is a slow moving snail that uses undulation and pedaling to move (Marine Invertebrates of Bermuda 2007).
