Kingdom:      Animalia Phylum:         Chordata Class:            Reptilia Order:           Crocodilia Family:          Alligatoridae Genus:           Caiman Species:         Caiman yacare

Until quite recently, this caiman was considered a subspecies of Caiman crocodilus and known by the name Caiman crocodilus yacare.

Yacare caiman conservation statusEdit

Caiman yacare is listed as Least Concern on the IUCN Red List of Threatened Species.

The estimated wild population is comprised of 100,000 to 200,000 individuals.

Although being depleted compared to historical populations, the Yacare caiman is still widely distributed and ranching and sustainable yield programs exist in several countries. Illegal hunting during the 1970s and 1980s had a significant negative impact on this species and organized poaching remains a problem in parts of its range. Habitat destruction is also a risk.

Yacare caiman rangeEdit

The Yacare caiman is native to Paraguay, south-eastern Bolivia, south-western Brazil, and northern Argentina.

Yacare caiman habitatEdit

The Yacare caiman occurs in many different habitats, including lakes, rivers and wetlands. It seems to like floating mats of vegetation.

Yacare caiman size and appearanceEdit

The Yacare caiman reaches a length of 2.5-3 meters and its scales have well-developed osteoderms. The flanks are less ossified and therefore more popular on the hide market.

Yacare caiman feeding and dietEdit

The Yacare caiman feeds chiefly on aquatic invertebrates and vertebrates, e.g. snails, mollusks, crustaceans and fish. Snails make up a significant part of its diet. It is also known to occasionally catch and eat snakes and large specimens can take mammals like the capybara. The Yacare caiman is sometimes referred to as the Piranha caiman due to its appetite for Piranha fish.

Yacare caiman breedingEdit

For this species of caiman, the middle of the rainy season is peak time for egg laying while hatching occurs in March. A mound nest is constructed in which the eggs are laid and the clutch size varies from 21-38 eggs. The female will normally guard her nest while the eggs incubate, but females living in areas with a high hunting pressure are known to abandon the nest once the eggs have been laid.
