Dwarf Caiman - Paleosuchus palpebrosus
Also named Cuvier’s Smooth-fronted Caiman, Paleosuchus palpebrosus (Crocodylia - Alligatoridae) is a small, South American caiman, found near rivers and inundated savanna areas. This species is the smallest of the family. Males grow to about 1.3-1.5 meters, while the females grow to 1.2 meters.
Paleosuchus palpebrosus is a social species with diverse and interesting behaviors. Like most crocodilians, they can convey social messages through sounds, postures, movements, smells, and touch. Although most crocodilians are somewhat social, P. palpebrosus are typically found alone or in pairs.
Systematic studies of adults indicate that there are dominance hierarchies within groups. The most hostile and aggressive individuals appear to be the most dominant. These individuals control access to mates, nest sites, food, and living space. Dominance is asserted and maintained by social signals and displays.
