Resumo
Among the Brazilian crocodilian, Caiman crocodilus crocodilus is widely distributed, given its
adaptation to diverse habitats and their generalist diet. Information about the reproductive and
ethological character of this species is abundant, whereas morphological data are still scarce. This
study aimed to identify and report the muscles and their origin and the insertion into the pectoral and
forelimb of C. crocodilus crocodilus. We used two male specimens, adults, belonging to the collection
of the UFG – Jataí. We performed usual procedures for dissection and further individualization,
withdrawal of members, and observation of muscle origins and insertions. The musculature of C.
crocodilus crocodilus generally conservative is similar to C. latirostris and A. mississippiensis. The
muscles of the pectoral girdle showed little variation among crocodilians. In the forelimb, the triceps
muscle has five distinct heads and biceps has only one. The extensor and flexor surface of the hand
showed similar topography to A. mississippiensis. We described some differences in the origin and
insertion of certain muscles, as well as the classification and topography of some flexor and extensor
muscles in the forearm segment. The distal segments showed more variations, which probably reflects
the variety of locomotor habits among crocodilians.
