Definition of gular in US English:



  • Relating to or situated on the throat of an animal, especially a reptile, fish, or bird.

    • ‘These birds are highly adapted to aquatic life. They dive to catch most of their prey (crustaceans, small fish, and cephalopods), and have a gular pouch in which they can carry food.’
    • ‘First each lizard ran normally; then a plastic tube was inserted into the mouth to keep the animal's mouth open and prevent gular pumping.’
    • ‘By way of analogy, pelecaniforms also use large gular pouches for feeding young and in cooling behaviors, both entirely plausible behaviors for pareiasaurs.’
    • ‘Such a mechanism would have been analogous to expansion of the buccal and gular cavities of fishes and many tetrapods by the hyobranchial muscles acting on the hyoid arches.’
    • ‘Species with large gular sacs use them in conjunction with foraging, mating displays and thermoregulation.’


  • A plate or scale on the throat of a reptile or fish.

    • ‘The image of the ventral skull has been modified to include a median gular which is not in the original figure.’
    • ‘The median gular plate is large, extending the length of the orbit; it is ovoid and bears the usual two small pit lines fused into a V. Behind it, the paired lateral gulars are slightly wider than the first branchiostegal rays.’
    • ‘The gular occurs as a very large, unpaired, median plate.’
    • ‘As we discussed in connection with the gulars, the opercular series seems to have developed from serial repetition of a simple overlapping laminar series of scales, as exemplified in some Acanthodii.’
    • ‘Long remarks that Onychodus is primitive because, among other things, it has submandibular plates rather than branchiostegal rays, although it does possess gulars of a sort.’


Early 19th century: from Latin gula ‘throat’ + -ar.
