Black turban snail, black turban, black tegula, black top Tegula It is also part of the superfamily Trochoidea, presenting nacre as the inner shell layer, and its subordinated family Tegulidae. Most snails possess a soft, tube-shaped body, a muscular foot for locomotion, one or more pairs of tentacles emerging from the head, and small eyes at the top or the base of the main stalks. This adaptation means they can travel from water source to water source and can survive in polluted aquatic environments. Snails protect themselves from predators by taking coverage beneath their shells and through the use of the operculum, a door-like part that closes the opening of the shell. The umbilicus appears as a small but deep hole on the underside of the shell.
