Populations are also found in montane and highland environments at higher elevations.
Distributed across Comoros, Indonesia, Mozambique, and South Africa. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.
Onca
Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 6 distinct biome types spanning the Neotropic and Oceanian realms. Populations are also found in montane and highland environments at higher elevations.
Distributed across Colombia, Ecuador, and Venezuela. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.
Coelacanth
Um fóssil vivo considerado extinto durante 65 milhões de anos até ser redescoberto ao largo da África do Sul em 1938, os celacantos podem atingir 2 metros e 90 kg. Pertencem a uma linhagem ancestral de barbatanas lobadas mais relacionada com os tetrápodes do que com os peixes de barbatanas radiais, tornando-os cientificamente inestimáveis para compreender a evolução dos vertebrados. Encontrados em habitats de recifes rochosos profundos do Oceano Índico, são noturnos e sofrem fertilização interna, dando à luz crias completamente formadas. Em Perigo Crítico.
Onca
O maior felino das Américas, atingindo até 100 kg com corpo robusto e musculoso e pelagem com padrão de rosetas característico. Encontrado do México até a América do Sul, com populações mais expressivas na Amazônia e no Pantanal. Nadadores poderosos e predadores de topo, os jaguares desempenham papel fundamental na regulação das populações de presas. Classificado como Quase Ameaçado, com sua área de ocorrência diminuindo devido ao desmatamento.
