Celacanto

Un fósil viviente considerado extinto durante 65 millones de años hasta su redescubrimiento frente a Sudáfrica en 1938, los celacantos pueden alcanzar 2 metros y 90 kg. Pertenecen a un antiguo linaje de aletas lobuladas más relacionado con los tetrápodos que con los peces de aletas radiales, lo que los hace científicamente invaluables para comprender la evolución de los vertebrados. Encontrados en hábitats de arrecifes rocosos profundos del Océano Índico, son nocturnos y experimentan fertilización interna, dando a luz crías completamente formadas. En Peligro Crítico.
