The PPGZOO has attracted a growing number of applicants from several Brazilian states and abroad since its first selection process. This characteristic is certainly due to its innovative character regarding the applicability of zoological knowledge.

As part of the OAS program (PAEC OAS-GCUB) of Latin American exchange students for graduate studies in countries other than their countries of origin, the program receives, with its own scholarship, foreign students. From the PAEC program, PPGZOO has already received seven students, and currently the program has foreign students from Bolivia, Chile, Colombia, Ecuador, Honduras, Peru and Venezuela.
