Answer: tooth comb
Explanation: Strepsirhines are any member of the clade (a group of animals or other organisms derived from a common ancestor species) Strepsirrhini, one of the two suborders (a taxonomic category below order and above infraorder) of primates. They have a special lower incisor called a tooth comb which consists of long, flat teeth with microscopic grooves, and used for grooming the fur.
Strepsirhines, a suborder of primates that includes lemurs and lorises, have a distinct structure called a toothcomb, made up of closely packed lower incisors that stick out from the mouth. Apart from other unique features like a grooming claw, this toothcomb sets strepsirhines apart from other primates.
Strepsirhines, a suborder of primates that includes lemurs and lorises, have unique anatomical features that set them apart from other primates. They have incisors in their lower jaw that are packed closely together and stick out from the mouth in a structure called a toothcomb. This toothcomb, in combination with a clawlike second toe known as a grooming claw, is a hallmark of strepsirhines. The toothcomb is used for grooming - removing debris and parasites from their fur - and is also thought to assist in feeding.
Unlike the majority of mammals, which are diphyodonts and have two sets of teeth in their lifetime, strepsirhines' teeth do not necessarily get replaced. Strepsirhines are found primarily in the 'Old World' - parts of Africa, Asia, and Europe - though a number of species are indigenous to islands such as Madagascar.
