CGDP - Radulae
The radula is a ribbon of repeating tooth rows that the animal rasps along surfaces scouring for food. In cowries, the radulae
consist of rows of seven teeth, as seen below. Radular features, such as the number of cusps, presence or absence and positioning of
basal denticles and general tooth shape, have been used in cowrie systematics for over a century. There are some really cool aspects to
radular development that are currently being examined.
