Those canines are "primarily used to chew up wood and other tough foods" as per one of the articles, but male adult camels may also use those to bite opponents when fighting with each other for territory / mates.
"Someone once described them as a Sarlacc pit from Star Wars" ... definitely a fitting description.
Huh. I guess the camel mouth pictures I saw before have all their teeth extracted or something? Second pic absolutely looked like that of a large cat pic to the untrained eye (mine)
Fron what I've read, there are differences in breeds (alpacas for example have very small canines compared to other species), females have smaller canines than males (on average), and they're also usually removed / clipped for domesticated camelids (example with an alpaca: https://www.youtube.com/watch?v=vyXSrIUkFNg)
