Populations are also found in montane and highland environments at higher elevations.

Range

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.

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.

common bottlenose dolphin

A espécie de golfinho mais estudada e reconhecida, os roazes habitam oceanos quentes e temperados de todo o mundo, desde águas costeiras rasas até ao mar aberto. Altamente inteligentes com grandes cérebros em relação ao tamanho corporal, demonstram auto-reconhecimento, comunicação complexa e aprendizagem social. Vivem em sociedades fluidas de fissão-fusão e cooperam para arrebanhar peixes. Uma espécie indicadora chave da saúde dos ecossistemas marinhos.
