The Yacare caiman (''Caiman yacare'', ''jacaré'' in Portuguese) is a species of caiman found in central South America, including northeastern Argentina, Uruguay, southeastern Peru, eastern Bolivia, central/southwest Brazil, and the rivers of Paraguay. About 10 million individual Yacare caimans exist within the Brazilian ''pantanal'', representing what is quite possibly the largest single crocodilian population on Earth. As a medium to small to mid-sized crocodilian, most adult males grow to roughly in length, with the occasional individual (reports of individuals within the ''pantanal'' are yet to be verified). Females are rather smaller at an average of . Body mass in this species can range up to in males and from in females.〔()〕 Their relatively smaller size makes them a potential prey of the jaguar〔http://www.huffingtonpost.com/2013/09/27/jaguar-attacks-crocodile-caiman-video_n_4004616.html〕 and anaconda.〔http://www.discoveryuk.com/web/swimming-with-monsters/about/anaconda-facts/〕 This species' diet consists primarily of fish (especially piranha) and birds,reptiles,small mammals. with the occasional large mammals (especially capybara) being taken by larger adults. In general, due to their size, this species is not considered to be fatally dangerous to humans. ==Gallery== Yacare caiman (Caiman yacare) juvenile.JPG|Juvenile, about one month old, The Pantanal, Brazil Image:Caiman yacare Iberá.jpg|Iberá marshes, Corrientes, Argentina Image:Caiman yacare.jpg|Formosa Province, Argentina Yacare caiman (Caiman yacare) 2.jpg|The Pantanal, Brazil 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「yacare caiman」の詳細全文を読む スポンサード リンク
