They get attached to the intestinal mucosa via the buccal capsule.
2.
True teeth are unique to vertebrates, although many invertebrates have buccal capsule.
3.
While the ventral sets are prominent, the dorsal set is hidden deeper in the buccal capsule.
4.
The teeth of " A . caninum " are found in the buccal capsule and divided into three sets.
5.
They possess spicules ranging from 23-30 ?m in length and cup-shaped buccal capsules ( mouths ) that open at the anterior end.
6.
Whereas " A . duodenale " possesses two pairs of teeth, " N . americanus " possesses a pair of cutting plates in the buccal capsule.
7.
What differentiates this species from its congeners is the presence of marked cuticular excrescences on the anterior and posterior ends of the body and the location of the buccal capsule deeply inside the head end.
8.
It can be distinguished from its cogenerates by its head morphology, i . e . its lips or pseudolabia absence, a slitlike oral opening, and its buccal capsule being triangular shaped in the apical view.
