labial teeth

The fine labial teeth are prominent, their color is white or pale brown, and they cross the entire base, with dark brown spaces in between.

The labial teeth are visible on the outside, owing to the thinness and transparency of the shell.

The base may be white, purple or cream and the wide and sinuous aperture shows long labial teeth.

The long and wide aperture shows about 15 teeth on the columellar and labial teeth.

The tadpoles initially have three pairs of external gills and several rows of labial teeth.

The tadpole has neither an upper nor lower jaw sheath, but up to 17 rows of posterior labial teeth.

The margins and the extremities are clearer, while the base is generally white, with a wide sinuous aperture and long labial teeth.

Others have specialised mouthparts consisting of a horny beak edged by several rows of labial teeth.

The base of Macrocypraea zebra shell is pale brown and the long and narrow aperture usually bears long dark brown labial teeth.

They have wide caudal fins and two rows of labial teeth on the top of their mouths and four rows on the bottom.

The oral disc is nearly terminal and bears finely serrate jaw sheaths and two anterior and three posterior rows of labial teeth.

The mouths of the tadpoles are made for suction to rocks, with labial teeth rows used for scraping algae and diatoms, unicellular algae with cells walls that contain silica, off of the rocks to which they are clinging.
