moon snail Naticarius
Family Naticidae updated
seen? This moon snail with a spotted shell and pretty pattens
on its body is sometimes seen on clean sandy shores on some of our
Southern shores. Elsewhere it is found offshore on sandy bottoms. It was previously
called Natica onca.
Features: 1.5-2cm. Shell spherical
(not flat) with the spiral tip sticking out a little. Shell smooth
beige usually with 5 spiraling rows of dark brown bar or spots. On
the underside, a small circular depression. Operculum is shelly, with
regular grooves and pearly white. Foot transparent with a white margin
and a pattern of white bars and red spots, front part of the body
white with four wide red or orange bands (which appear as large spots
when the animal is fully expanded). Short red tentacles.
Some have been seen 'dragging' a small snail shell behind them attached
to the foot.
