* The Predator in, well, ''Film/{{Predator}}'' has two sets of Functionals. This carries over to the Predaliens in ''Franchise/AlienVsPredator''.

* ''Series/{{Supernatural}}'': Creatures from a parallel universe, [[AllThereInTheManual called "canids" in the script]], that were introduced in the Season 13 episode "Wayward Sisters" have mouths of this type. To use the words of the Supernatural wiki, "the canids mouth reveals a mandible that when opened reveals a beak with tendrils."

* ''Webcomic/ElGoonishShive'': Sirleck's jaws sort of... wrap around a human head, given that he's a body-hopping eldritch abomination parasite.

* In ''Webcomic/GrrlPower'', a minor character named Chorius has a set of Decorative.

* In ''Webcomic/{{Earthsong}}'', The Spinster is an anthropomorphic spider-like alien who reveals a set of mandibles to accompany his [[MoreTeethThanTheOsmondFamily fanged mouth]] on the rare occasions he shows his face. The implicit threat of doing so is part of why his species usually wears veils.
* ''Webcomic/RustyAndCo'': An ant-folk HiveQueen who was corrupted by an ArtifactOfDoom wears a concealing scarf when she's [[FauxAffablyEvil feigning affability]], but takes it off to [[http://rustyandco.com/comic/level-9-26/ reveal]] jagged mouthparts with large mandibles when she gives the order for a character to be killed. Her [[PunchClockVillain subordinates]] only have small mandibles or none at all.

* In ''Anime/{{Berserk}}'', Rosine's "children" are tiny humanoids who look like fairies. However, when angry their mouths spit sideways into insectile mandibles, revealing them as wasplike monsters.

* The volatiles from ''VideoGame/DyingLight''
* The eponymous metroids of ''Franchise/{{Metroid}}'' have Replacements, with one set used to hold onto prey and another set for the actual life-drinking.

* Larger zerg, particularily hydralisks, in ''Videogame/StarcraftII'' have a hybrid between Functional and Bifurcated, with an outer set of jaws splitting apart.

* The turians in ''Videogame/MassEffect'' are covered in bony plates which form beak-like protrusions, bony heel spurs, and spiky crests as well as Functional mouthparts on either side of their jaws, giving them beak-like points in place of lips, needle-like fangs, and insect-like mandibles. In spite of this, they're possibly the alien species with which humans actually have the most in common.
* ''VideoGame/DivinityOriginalSinII'': The [[TorturedMonster Lamenting Abomination]] looks like a grotesque ShapeshifterMashup whose mouth is composed of the upper jaws of at least five wolves, stitched haphazardly together.

* ''VideoGame/DivinityOriginalSinII'': The [[TorturedMonster Lamenting Abomination]] looks like a grotesque ShapeshifterMashup with multiple mismatched sets of jaws flapping around its mouth.

* Mister Scroop from Disney's ''Disney/TreasurePlanet'' has a pair of ant-like mandibles added onto a conventional maxilla-and-mandible mouth, qualifying as Decorative. They fit well with his arachnoid body, six walking legs and irisless eyes. They're appropriate for a character who's TheDragon of a cutthroat pirate band.

For creatures where these are almost universal, see InsectoidAliens, BigCreepyCrawlies, and PredatorPastiche. Very closely related to FlowerMouth, wherein several jaws ring the throat in defiance of the typical maxilla-mandible setup, a situation which closely resembles multiple sets of jaws.

# '''Replacement''': This is total replacement, where Monstrous Mandibles are the only mouth parts. These are the default in InsectoidAliens and more commonly found on particularly strange creatures.

* The elites in ''Videogame/{{Halo}}'' have two sets of jaws. Depending on how one looks at it, it could either be two sets of Bifurcated, two of Functional, or one set of each.

* Many snakes actually have a Bifurcated type with their lower jaw, though the connective tissue of their mouth means it looks like one piece until you see the skeleton. Many monitor lizards have the same arrangement. In both cases, this allows the animal to stretch their jaws wind in order to swallow large prey.
