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.
