How many teeth do Plecostomus have?

Plecostomus, a type of Freshwater Fish known for their algae-eating habits, have a unique dental structure. They do not possess traditional teeth like many other fish; instead, they have small, tooth-like structures called "pharyngeal teeth" that are used to scrape food off surfaces. These structures are adapted for their herbivorous diet, allowing them to efficiently consume algae and other plant material. The exact number of these teeth can vary, but they are typically not counted in the same way as standard teeth.
