Atlantic Bluefin Tuna

O atum-rabilho-do-Atlântico (Thunnus thynnus) é um dos peixes mais grandes, mais rápidos e de maior valor econômico do mundo, com indivíduos que podem ultrapassar 600 quilogramas. Seu estado de conservação é em perigo (EN) e suas populações silvestres diminuíram drasticamente pela sobrepesca, tendo sido leiloado um único exemplar de qualidade por mais de três milhões de dólares no Japão.

Baleia jubarte

Entre as baleias grandes mais acrobáticas, as baleias-jubarte são famosas por seus cantos complexos e evocativos entoados pelos machos durante a temporada reprodutiva, podendo durar horas e evoluir ao longo do tempo. Atingindo 16 metros e 30 toneladas, realizam as migrações mais longas de qualquer mamífero. Encontradas em todos os oceanos, alimentam-se de krill e peixes pequenos usando a técnica cooperativa de rede de bolhas.
