Reproductive biology and food habits of Pseudoboa nigra (Serpentes: Dipsadidae) from the Brazilian cerrado
Herein we provide data on body size, sexual size dimorphism, reproductive cycle, and food habits of the pseudoboini snake Pseudoboa nigra, which is distributed mainly in central South America throughout the Cerrado domain. Based on dissections of 147 preserved specimens, it is shown that females att...
