Field Observation of Egg-laying Behavior of a Puddle Frog Occidozyga sumatrana from Bali, Indonesia (Anura: Dicroglossidae)

Abstract

Occidozyga sumatrana is not uncommon in some parts of Southeast Asia but its reproduction in nature is poorly known. We observed egg-laying behavior of this species in Bali, Indonesia. The amplectic position was inguinal and the oviposition site was out of the water in O. sumatrana, both of which are unique given its phylogenetic position and the mainly aquatic habits of adults.
