Final answer:
A dental comb is found in lemurs, which are part of the Strepsirrhini suborder of primates, known for their distinctive comb-like dental structure.
Step-by-step explanation:
The dental comb is a specialized structure in the dentition of certain primates, including the lemurs. This feature is characterized by lower incisors and canines that are tightly packed together and protrude forward, creating a comb-like arrangement used for grooming. Lemurs belong to the Strepsirrhini suborder, which encompasses the primates that possess this unique dental morphology.
