General abbreviations and symbols: (?) symbolising uncertainties; (*) symbolising a connection to foods exceeding the oral cavity; (¹) limited functionality; (²) the induced metamorphosis in Ambystoma mexicanum seems to result in a hyobranchial configuration that does not permit pronounced tongue projection; (³) prey dusted with a calcium powder; (AC) arcuate chewing, “simple” chewing using open-close movements of the jaws; (aqua) aquatic, signalling that feeding occurred under aquatic conditions; (DCC) dimensionally complex chewing; (Hydro) hydrodynamic food transport; (Hyo) hyobranchial food transport; (JP) jaw prehension; (PS) prey shaking; (RF) rotational feeding, (SF) suction feeding; (terr) terrestrial, signalling that feeding occurred under terrestrial conditions; (LP) lingual prehension; and (TPR) tongue-palate rasping. Food items: (B) beatle, unspecified; (BlaW) black worm, Lumbriculus variegatus; (BloW) bloodworm, larva of chironomids; (CF) crayfish, freshwater crustaceans from the clade Astacidea; (CR) cockroach, unspecified; (EW) earthworm, unspecified; (F) fish, unspecified; (FF) fruit fly, Drosophila sp.; (HC) house cricket, Acheta domesticus; (IL) insect larva, unspecified; (LS) land slug, unspecified; (M) maggot, larva of Lucilia caesar; (PF) pellet food; (SFL) soldier fly larvae, Hermetia illucens; (SiW) silkworm, larva of Bombyx mori; (SS) sea snail, Acochlidium sp.; (SW) sludge worm, Tubifex sp.; (T) termite, unspecified; (WF) Cladocera, unspecified; (WL) woodlouse, Porcellio sp.; (WW) waxworm, larva from pyralid moths, Pyralidae. Note that a μCT-based determination of the morphotype was only possible in a few species; the majority were assessed based on a combination of external characteristics and descriptions from literature.;Feeding sequence from ingestion to the onset of swallowing. Note the similarity between processing (0:07) and anterior transport (0:19) of food.
