denticle

The base of the shell has a minute internal denticle.

Similar scales can also be found under the head of the denticle herring.

It seems to have a simple cusp, without the sharp denticle of the preceding species.

That one denticle has a central cusp and a few surrounding cusps.

It has a large reflected cusp with one strong median denticle and two smaller ones on each side.

Each denticle has three horizontal ridges that lead to teeth on the posterior margin.

There is a pointed spine in the centre, and 6 or 6-7 smaller spines on each side of the denticle.

The two species also differ in denticle coverage and meristic counts.

Each denticle is thorn-like in shape, with ridges radiating out from the central point over the base.

Each denticle has an arrowhead-shaped crown with three posterior points, mounted on a short stalk.

The upper palatal lip often has a small tuberculate denticle.

The sinuous columella terminates in a point or denticle at its base.

The extent of denticle coverage and number of oral papillae can vary among individuals.

The broad columella is concave, with a conspicuous fold near the base and a small denticle above it.

Fairhurst was inspired by the dermal denticle structure of the skin of sharks.

The columella has a strong denticle.

Into Brody's palm Hendricks dropped a triangle of glistening white denticle.

The hatchlings seem to lack the specialized denticle used by other swellsharks to break out of the egg case.

Additionally, the teeth of Troodon bore large serrations each of which is called a denticle.

Small, overlapping dermal denticles cover the body and fins; each denticle has three marginal teeth.

Larvae are well-equipped for grazing, with an inferior oral disc consisting of a beak and 6-7/7-10 denticle rows.

The parietal callus is appressed and devoid of a parietal denticle.

Each denticle is diamond-shaped, with 3-5 horizontal ridges leading to marginal teeth in smaller individuals, and 5-6 in larger ones.

The radula formula is 0+1+0, which means that there is only a single central denticle in each row.

The inside of the lip of the shell has 15-25 small irregular denticles, plus one very strong isolated denticle near its posterior end.
