ABSTRACT We present, for the first time, suction feeding behavior of tadpole Dendropsophus cerradensis (Hylidae, Dendropsophini), along with a detailed description its external morphology, buccopharyngeal cavity, and musculoskeletal system. The exhibits depressed body, anteriorly positioned nostrils, modified oral disc (completely covered by folds), low tail, resembling other members D. microcephalus group. cavity is reduced in features, internal nares at an acute angle prenarial papillae, exclusive this species. Muscle insertion patterns are generally consistent Dendropsophini tadpoles, except m. levator mandibulae longus profundus on Meckel's cartilage. characterized use tube that protrudes exclusively during predation. This mechanism may be associated robust mandibular hyoid musculature, as well cranial structure—including unique suprarostral element, quadrangular muscular processes, ceratohyals, branchial basket hyobranchial skeleton—which enables fast movements. study presents previously unknown aspect protractile group, providing new insights into morphology
