The skeletal system of developmental stages and the adult of Smilisca baudini is described, and the skull is compared with that of other members of the genus.
The tadpoles are described, compared, and illustrated; the larval development of Smilisca phaeota is described.
Breeding behavior and breeding calls are described and compared. Some species of Smilisca have breeding choruses. Two species, S. sila and sordida, breed in streams, whereas the others breed in ponds.
The genus is considered to be part of the Middle American Faunal Element; the species are thought to have differentiated in response to ecological diversity and historical opportunities provided by Cenozoic changes in physiography and climate.
