Seabird species include tufted puffins, the endangered short-tailed albatross, spectacled eider, and red-legged kittiwakes. The yacare caiman is ecologically similar to the spectacled caiman. In South America, feral dogs, jaguars, anacondas, and spectacled bears are threats to livestock. There are several records of American crocodiles killing and eating spectacled caimans in South America. They coexist with the smaller spectacled caiman within Central America. The spectacled caiman is a small to medium-sized crocodilian. Usually hunting at night, the diet of the spectacled caiman varies seasonally. When he was 15, he also owned young spectacled caiman. It has osteoderms on its scales, a feature also present in the spectacled caiman. The only predators of cubs include cougars ("Puma concolor") and possibly male spectacled bears. It sometimes preys on spectacled bear cubs. An exception is the spectacled bear; native to South America, it inhabits the Andean region. The hundreds of mammals include rare species like the puma, jaguar and spectacled bear. Only a single Burmeister's porpoise and a single spectacled porpoise have been kept in captivity. The best habitats for spectacled bears are humid to very humid montane forests.
