Description

[ Back to top ]

Habitat

Found in a variety of habitat types , similar to Caiman crocodilus - wetlands, rivers and lakes . Often associated with floating mats of vegetation. Has the southernmost distribution of all caimans.

Ecology: The yacaré caiman is found in southern Brazil and Bolivia, southwards through the Paraguay/Paraná River systems and into northern Argentina. Morphologically and ecologically this species is very similar to the common caiman, and similarly can be found in a wide spectrum of habitat types . Most of the ecological studies on this species have been carried out in the Pantanal region of southern Brazil (Crawshaw and Schaller 1980, Schaller and Crawshaw 1982, Cintra 1986). More recent studies also include Bolivia (Pacheco 1993a, Godshalk 1994). Nesting habitats were monitored during the incubation and hatching period (Borges and Filho 1993), and the effect of water level on hatchlings survivorship have also been evaluated (Continho 1993). Aerial surveys of caiman nests have been started in the Pantanal (Mourao et al. 1994).

Biology

Diet

Aquatic invertebrates (particularly snails) and vertebrates such as fish with the occasional snake .

Reproduction

Yacaré caiman are mound nesters , with egg-laying usually peaking in the middle wet season . Clutch size is typically in the 25 35 range . The natural tendency of females to guard their nests is apparently influenced by human hunting pressure (Crawshaw 1987), which results in decreased nest attendance and a lower hatching success.
