Family Tonnidae
Tun Shells
Tuns are large thin snails with soft parts too large to retract into the
shell. There is no operculum. They emerge from sand at night to feed upon sea cucumbers.
Live animals are rarely seen by divers except at night and appear to be
more common in very deep water where hermit-crabbed specimens are
trapped.
Egg masses are coiled gelatinous ribbons with rows of beige eggs. |
