They are totally different to Catostomus. Pantosteus usually live in
places with clearer water and hard substrates, they use their
cartilagenous sheath inside their mouth to scrape algae and other critters
off rocks, but they will also eat inverts as well I guess (there are some
studies on diets, but I'm not massively familiar with them). It's is
generally thought that algae and other "stuff" growing on rocks is an
important component, and I've often seen them scraping rocks in the wild.
