The larval shell shows some intraspecific variations in adults. It is glassy, low, and rounded to mucronate. This seems to be related to the protection of the pseudopallium when it is immersed inside the respiratory tube. The juvenile develops the pseudopallium relatively early, when it has 1.5 whorls, and protects the shell from this stage onwards; at the same time, it is attached to an area of the
