blue whale

O maior animal que já viveu na Terra, as baleias-azuis podem atingir 33 metros e 200 toneladas — seus corações sozinhos pesam tanto quanto um carro pequeno. Encontradas em todos os oceanos, migram entre áreas de alimentação polares e áreas de reprodução tropicais. Filtradores que consomem até 4 toneladas de krill diariamente. Em perigo, com populações globais estimadas em 10.000–25.000 após a quase extinção causada pela caça baleeira no século XX.
