This program is designed to introduce Primatology students to the range of monkeys of the Super family Ceboidea originating from Central and South America. Material on twenty -two species is included, covering all five of the families recently defined by the International Union for the Conservation of Nature. Some material was taped in the wild, while other species were observed in semi-free ranging and caged locations. The program begins with a brief introduction of the five families and then shows the field location in Costa Rica where some material was gathered. Morphological traits distinguishing New World from Old world forms are indicated throughout the first few segments. Short clips of marmoset and tamarin species cover a variety of forms while more in-depth segments on other species allow students access to different levels of information. In this video we are provided with a wealth of information about size, habitat, range, sexual dimorphism, diet, and communication patterns of each species. There is also footage of mother/infant interaction and adult social relations. Some maps and diagrams are included to inhance understanding of particular topics. A self-guide study sheet is included. This program is suitable for both introductory level and as a focus for discussion by more advanced students.
