In anatomy, the soft area under the chin and lower jaw of certain animals, especially reptiles and birds.
From Latin 'gula' meaning 'throat' or 'gullet,' which may derive from Proto-Indo-European roots meaning 'to swallow.' The term is primarily used in zoological anatomy.
The gula in birds and reptiles is key to identifying species — ornithologists and herpetologists study the gula's color, pattern, and scale arrangement the way detectives study fingerprints, because it's that specific to each animal.
